Tessellation Sew Along – Week 4



Welcome to week 4, as we sew up the Tessellation quilt pattern by Alison Glass and Nydia Kehnle. If you’re following along, I hope you’ve been enjoying yourself, and if you’re jumping in late, welcome aboard!

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!!



And we’re moving right along to all of the ‘D’ triangles. This is the fastest and easiest triangle to assemble, with only 3 fabrics needed.


First, I placed my fabric #1 and fabric #2 right sides together, making sure that they overlapped segment 1 and segment 2 on the printed template by 1/4″. You can use your light source or fold at that line to make sure that your second fabric will cover segment 2. Sew directly on top of the line connecting segment 1 and segment 2. If necessary, trim the seam allowance to 1/4″ and press fabric 2 toward the 2nd segment.


Add a 3rd fabric strip. I decided to make my ‘D’ triangles all in the same color family, going from light to dark. Make sure fabric #3 overlaps the line between segment 1 and segment 3 by 1/4″. Trim the seam allowance to 1/4″ and press fabric 3 toward segment 3.



After sewing all 3 fabrics, your template should look sort of like this.


Using your ruler and rotary cutter, flip to the printed side of the template and trim the fabric even with the paper.

Only 2 triangles left! Stay tuned next week as we work on all of the ‘E’ triangles!

Don’t forget to tag your progress on Instagram, Twitter, or Flickr using #TessellationSAL and #alisonglass !

    can you tell me what size you cut your segments into? i’m wanting to use as little fabric as necessary and am not experience enough to give an educated guess without some trial and error. i appreciate your help with this and the other blocks.

    I thought I was up to date but am a week behind and now will be gone this next week. However, I love what I am creating. Thanks for this SAL Sara! I do have a question: are you trimming all your seam allowances to 1/4 inch?


Comments make my day and I love to reply!
