Tessellation Sew Along – Week 3



Welcome to week 3, as we sew up the Tessellation quilt pattern by Alison Glass and Nydia Kehnle. Happy to have you join in at any time!

Every Monday, I will post a quick photo tutorial for each week’s block for those of you that are new to foundation paper-piecing (however, you will still need to purchase the pattern in order to complete the quilt – I will not be providing any templates on my blog).

If you are sewing along, feel free to post your progress photos on your preferred social media (Instagram, Twitter, Flickr, etc.) and use the tag #TessellationSAL and #alisonglass so we can see what you’re making!

The schedule:

  • July 14 – Get your pattern (and optional triangle ruler) here. Select your fabric, and begin by cutting all ‘A’ triangles.
  • July 21 – Assemble all ‘B’ triangles.
  • July 28 – Assemble all ‘C’ triangles.
  • August 4 – Assemble all ‘D’ triangles.
  • August 11 – Assemble all ‘E’ triangles.
  • August 18 – Assemble all ‘F’ triangles.
  • August 25 – Complete the quilt top. I’ll share some ideas for quilting.
  • September 1 – Enter your completed quilt top to be eligible for PRIZES!!



For week 3, we will be working on all of the ‘C’ triangles. Make sure to make the appropriate number of copies of the template, and we’re off!


First, we’ll be working with one of the rectangles and the 5″ strip. Place the printed side of the template face down on a table. The 5″ strip should overlap the printed segment 1 and segment 2 by approximately 1/4″. Flip to the printed template and sew directly on top of the line connecting segment 1 and segment 2. Trim the seam allowance to 1/4″, then press the 5″ strip toward segment 2.


Here’s what it should look like after it’s pressed.


Now you’ll be adding the 6″ strip. For my layout, I decided to make my 5″ and 6″ strip the same color, but do what looks right to you! The 6″ strip should overlap the line between segment 1 and segment 3 by 1/4″. You may find it helpful to fold at the line with this block, since we’re working with skinny strips and you’ll want to make sure only to overlap that line by 1/4″ and not much more. Sew on top of the line between segment 1 and segment 3, trim the seam allowance, and press the fabric toward segment 3.


Now take the 7″ strip and overlap the line between segment 2 and segment 4 by 1/4″. Sew on top of that line, trim the seam allowance to 1/4″, and press.


The last strip to add is the 8″ strip, which will be placed in segment 5 of the layout.



After all 5 pieces of fabrics are sewn, your block should look like this. Turn to the printed side of the template and use your rotary cutter to trim the fabrics even with the paper.


Finish all of your ‘C’ triangles and we’ll hop over to the ‘D’ triangles next Monday!
