Summer on the Coast -- Month #2 -- Unit B

Welcome to our second month of the Summer on the Coast QAL!


This month we are making slightly more complicated blocks -- triangle in a square blocks! Click here to download the Craftsy pattern!

Here's how many units you will need for each size and approximate fabric needed for each part of the block:

Baby: 34 units (7/8 yard for large triangles, 1 yard for small triangles)
Throw: 48 units (1 yard for large triangles, 1 1/8 yard for small triangles)
Twin: 98 units (2 yards for large triangles, 2 1/4 yards for small triangles)

If you want to pre-cut your pieces to help reduce some trim-off waste, my recommendations for cutting is as follows:

Center triangles: cut 7 inch wide strips across your WOF. See below on how to cut your first angle -- you should be able to get 10 triangles per WOF.
Side triangles: cut 7.5 inch by 4.5 inch rectangles -- you will need to cut half of your rectangles from upper right to lower left and cut the other half of your rectangles from upper left to lower right. You will need one of each type of small triangle (left handed, right handed) for each unit.

Note: pre-cutting is NOT necessary if you feel confident in your paper piecing skills! 



To start, fold your triangle-square units along one of the triangle lines.use that fold to trim the same angle across your 7 inch fabric strip. I cut my strip 1/4 inch away from the edge of the paper. This will make it easier to line up your small triangles.


As noted above, you will need to cut both "left handed" and "right handed" half-rectangle triangles. If you layer two rectangles wrong sides together and cut diagonally once, you will have both two sets of triangles.



If desired, pin your fabric strip to the foundation. Line up your first triangle to the pre-cut edge and sew on the line. Press your triangle away from the background strip.



Fold along the opposite triangle line and cut off the excess background fabric strip - don't forget to leave a 1/4 beyond the fold for your seam allowance!


Place your second small triangle along the second angled edge and sew on the foundation line. Press your block.


Make sure that your triangles cover the entirety of the block as indicated by the dashed lines around the block. You may need to increase the size of your half-rectangle triangles if you have trouble with lining up the triangles correctly. When you've made sure that your pieces are lined up, you can trim your block along the dotted lines for a 6.5 inch block (6 inch finished).

  4. I'm finally getting around to working on these tomorrow morning. Trying to pick out the fabric ... am I right in reading that the center triangles are the "background" material. No biggie. Thanks!
