STEP 1 ~ PREPARING THE PATCHWORK
1a. Take your charm squares and cut them into 6.5cm (2.5″) squares. Assemble the patchwork by sewing straight columns/rows, using a 0.5cm (1/4″) seam allowance. Make the following:
STEP 2 ~ CUT OUT YOUR FABRIC
From the Exterior Fabric
(5-1/2″) tall by 14cm (5-1/2″) long. These will be your Exterior Side Panels.
2f. Using the Flap pattern piece, cut 1 on the fold. This will be your Interior Flap.
2g. Cut a piece measuring 14cm (5-1/2″) tall by 35.5cm (14″) long. This will be your Interior Bottom Panel.
2h. Cut 2 each, with each piece measuring 14cm (5-1/2″) tall by 14cm (5-1/2″) long. These will be your Interior Side Panels.
2i. Cut 2 pieces, each measuring 12cm (4-3/4″) x 55cm (22″). These will be your Zipper Panels.
From the Fusible Woven Interfacing
2j. Repeat Steps 2e. through 2i.
From the Fusible Fleece
2k. Repeat Step 2i. Also cut 1 Main Panel and 1 Flap. Cut 2 small 5cm x 5cm (2″ x 2″) scraps of fleece as well.
From the Vilene 520/Pellon 520F
(if you are using heavy sew-in interfacing instead, please cut Step 2l. as 1 layer of fusible woven and 1 layer of heavy sew-in; you will trim the heavy sew-in by 1cm (1/2″) on all sides. For all future instructions referring to Vilene 520/Pellon 520F, you will do this instead: place the heavy sew-in against the wrong side of your fabric, centered. Follow that with one piece of fusible woven interfacing, with the fusible side against the heavy sew-in. Fuse in place, sealing the heavy sew-in against your fabric).
2l. Cut 2 each of the Main Panels, 1 each of the Flap, 2 each of the Side Panels, and 1 each of the Bottom Panel.
STEP 3 ~ FUSE YOUR FABRICS
3a. Take 1 Interior Main Panel and one of the corresponding fusible woven interfacing pieces. Fuse the woven interfacing to the wrong side of the Interior Main Panel using manufacturer instructions. Repeat for 2 more Interior Main Panels. Also repeat for the Interior Bottom, the Interior Flap, and the Interior Side Panels.
3b. Take the remaining Interior Main Panel and one of the Main Panel pieces cut from Vilene 520/Pellon 520F and fuse to the wrong side of your fabric following manufacturer instructions. Repeat for only 1 of the Exterior Main Panels, the Exterior Flap, the Exterior Bottom, and the Exterior Side Panels.
3c. Use the remaining Exterior Main Panel and one of the corresponding fusible woven interfacing pieces. Fuse the woven interfacing to the wrong side of the Exterior Main Panel. Then fuse the fusible fleece against the fusible woven interfacing. Repeat for the 2 Zipper Panels.
STEP 4 ~ ASSEMBLE THE FLAP
4a. Take your Interior Flap. Fold it in half, lengthwise, and lightly finger press the crease. Make a mark with your fabric marker that is 5cm (2″) down from the longest straight edge.
4b. You will be using the smaller half of the magnetic snap. Take out the washer and place it on the mark that you made on the Interior Flap. Make a mark, using the washer, where the slits are to go. Use your scissors and cut small slits where the marks are. Repeat this for the center of one of your 5cm x 5cm (2″x2″) scraps of fleece. The reason that you are using the fleece is that it will help to reinforce your fabric against the pull from the magnetic snap every time you open and shut the flap.
Helpful Hint: I like to put a dab of Fray Check on the slits that were cut. I feel this helps the fabric hold up a bit better under the stress of the magnetic snap.
4c. Slide the prongs of the snap through the right side of the Interior Flap. Place the fleece square, then the washer, over the prongs. Close the prongs outward (use pliers with a piece of scrap fabric over the metal, if you need to), making sure they lie flat.
4d. Take your Exterior Flap and your Interior Flap, and place them right sides together. Sew along the curved edge using a 0.5cm (1/4″) seam allowance (do not sew the straight edge). Notch your seam (cutting small v’s every 1cm or 1/2″), being careful not to cut into the stitching. Turn your fabric right side out and press.
4e. Topstitch the Flap, 0.3cm (1/8″) from the edge, along the edge that you sewed in Step 4d.
STEP 5 ~ ASSEMBLE THE OUTER POCKET
5a. Take the Exterior Main Panel piece that you interfaced with the fusible fleece, and the remaining half of the magnetic snap. Fold the Exterior Main Panel in half and finger press a crease to find the center. The measure up 18cm (7″) from the bottom of the Exterior Main Panel and make a mark intercepting the center point. Insert the other half of the snap, using the same method that you used for the Flap.
5b. Take the Exterior Main Panel piece from Step 5a., and 1 of your Interior Main Panels. Trim 1cm (1/2″) off the top of each piece (the top is the slightly shorter edge). With the 2 pieces right sides together, sew along the edge that you just trimmed.
5c. Turn your panels right sides out and press. Topstitch 0.5cm (1/4″) along the finished edge.
5d. Place the panels that you just sewed, against the right side of the Interior Main Panel that is interfaced with the 520 interfacing. The bottom, unfinished edge of the panels should be even with the bottom of the Interior Main Panel. Baste in place along both side edges and the bottom edge.
5e. With the exterior side of the Flap facing you, baste the long, unfinished edge of the flap with the top of the Interior Main Panel from Step 5c. Check to make sure that the snap closes properly. This unit will now be referred to as one of the Exterior Main Panels.
5f. Take the completed Exterior Main Panel with the flap, and one of your handles. Place the left end of the handle up 12.5cm (5″) from the bottom and over 6cm (2-1/2″) from the left. Make sure your handle tab is free of the flap so that you are able to open and close it (the strap will be on top of the flap while you are wearing the bag). You may need to adjust the placement depending on the handles you have chosen. Sew the handle tab in place. If your tabs are thick, you may need to hand-crank your needle, or even hand sew. Repeat to secure the right end of the handle. Repeat this step for you remaining Exterior Main Panel and the other handle.
The handles will be stitched through a small portion of the pocket; this is important so that the stitches go through the Vilene 520/Pellon 520F to add stability to the area where the handle tabs are.
STEP 6 ~ INSERT THE ZIPPER
6a. Take your Exterior Zipper Panel and cut it in half, lengthwise.
6b. Place the resulting 2 pieces right sides together. With your fabric marker, measure and make a mark that is 2.5cm (1″) in from that left-hand edge. Do the same for the right-hand edge. Sew from the mark to the corresponding edge (each line of stitching will be only 2.5cm or 1″ long), using a 1.5cm (5/8″) seam allowance.
6c. Set your machine to a basting stitch. Baste, using a 1.5cm (5/8″) seam allowance, in between the 2 lines of stitching from Step 6b. Press the seam open.
6d. The wrong side of your Exterior Zipper Panel should be facing you. Take your zipper and place it face down on top of the Zipper Panel. The zipper teeth should be approximately on top of the basting stitches. Pin in place.
6e. Put the zipper foot on your sewing machine, and sew along 1 long edge, pivot, sew the short edge, pivot, sew the remaining long edge, pivot, and finally sew the remaining short edge. You should sew approximately 0.5cm (1/4″) away from the zipper teeth.
6f. With the right side of the Exterior Zipper Panel facing you, remove the basting stitches with your seam ripper.
STEP 7 ~ ASSEMBLE THE EXTERIOR
7a. Place 1 of your Exterior Side Panels in front of you. Make a mark at the top of your Exterior Side Panel, that is in 2cm (3/4″) from the top left-hand corner. Draw a line from the mark you made, down to the bottom left-hand corner of the Exterior Side Panel. Repeat for the right-hand side of the Exterior Side Panel.
7b. Take 1 Exterior Side Panel and your Exterior Zipper Panel. Place them, right sides together. The short edge of the Exterior Side Panel should be even with the short edge of the Exterior Zipper Panel. Sew along the short edge, and press the seam toward the Exterior Side Panel. Topstitch on top of the Exterior Side Panel, both 0.5cm (1/4″) and 0.3cm (1/8″) from the seam that you sewed in this step.
7c. Repeat Step 7b. for the remaining Exterior Side Panel, and the other end of the Exterior Zipper Panel.
7d. Take one of your Exterior Main Panels and the assembled Side Panel. Place the long edge of the Side Panel flush with the outer edge of the Exterior Main Panel, starting at the bottom left-hand corner of the Exterior Main Panel. Pin in place, moving up the side of the Exterior Main Panel. When you get to the top left-hand corner of the Exterior Main Panel, ease the Side Panel around the corner, then continue across the top of the Exterior Main Panel. Ease through the top right-hand corner as well, and continue until you have reached the bottom right-hand corner of the Exterior Main Panel.
Helpful Hint: I found it easier to sew the sides first, then the top of the bag, leaving the corners for last. I was able to more evenly distribute the side panel when attaching it to the exterior panels.
7e. Sew along the edges that you just pinned. Notch (cut small v’s) the seam allowance at both of the top corners. Press seams open.
7f. Repeat Steps 7d. and 7e. for the remaining Exterior Main Panel.
7g. Unzip your zipper (this is important so that you will be able to turn your exterior right sides out). Take your Exterior Bottom Panel and place it underneath your assembled Exterior. Line up the raw edges of both, making sure the corners are even, and pin in place.
7h. Sew along one of the short edges, starting and stopping 1cm (1/2″) from the corner. Repeat for the other short edges and both long edges. Trim the bottom corners, being careful not to cut into your seam allowance.
STEP 8 ~ ASSEMBLE THE INTERIOR
8a. Repeat Step 6a. and Step 6b. for the Interior Zipper Panel.
8b. Press the seam allowance of the long edge of the Interior Zipper Panel to 1cm (1/2″) (the center of the panel will be unsewn, but press the entire long edge anyway).
8c. Repeat Steps 7a. through 7h. with all of the interior pieces, except you will be using a 1.5cm (5/8″) seam allowance. This is important so that your interior will sit more snug inside the exterior of the bag.
8d. Turn your exterior right side out and your interior wrong side out. Place the interior inside of the exterior (so that wrong sides will be touching). Pin in place in several randomly-chosen areas, and also pin the pressed edges of the Interior Zipper Panel against the wrong side of your zipper.
8d. With your hand sewing needle and coordinating thread, hand sew the pressed edge of the Interior Zipper Panel from Step 8b., to the wrong side of your zipper. You may also wish to hand sew a few stitches on the right side and the left side of the bag to hold the interior in place.
