Island Chain - Session 2 - Combination Square Triangles February 03 2020

This session you will be making 144 combination-square-triangles.

 

 

You will need:

              - the pattern: Island Chain by Eye Candy Quilts 

              - cut fabrics A, B & C

              - a rotary cutter with a sharp blade

              - cutting mat

              - a ruler

              - pins

              - pencil or fabric marking pen

              - optional: Tucker Trimmer by Studio 180 Design Ltd.® 

              - optional: rotating cutting mat (available online HERE)

The instructions for the combination-square-triangles can be found at the bottom of page 2 of your pattern. The following is a step-by-step interpretation.

1. Draw a diagonal line on the wrong side of a B square.

2. Position an A square right sides together with the above B.

3. Sew a scant ¼” on each side of the drawn line.

4. Slice the unit in half on the drawn line. You now have 2 half-square-triangles.

5. There are 3 general rules about pressing when making a block.

           1 - Press...Do not iron!

           2 - Press to the dark side.

           3 - Or, press to the less busy side... meaning the side that has the least seams.

We will press the seam allowance to the dark side. After pressing, DO NOT TRIM the squares.

6. Draw a diagonal line on the wrong side of a C square.

7. Position the C square right sides together with one half-square-triangle being sure the drawn line is perpendicular to the seam line.

8. Sew a scant ¼” on each side of the drawn line.

9. Slice the unit in half on the drawn line.

10. Press to the less busy side. In this case, towards C. You now have 2 combination-square-triangles. 

11. Repeat steps #7 to #10 with the other half-square-triangle. There will be a total of 4 combination-square-triangles.

12. Square the combination-square-triangles to 3½”.

When using a Tucker Trimmer, position the half-moon symbol at the top right and line up the 45° line on the long seam line. Also, position the perpendicular 3½” dashed line on the other seam. This will ensure that the intersection of seams will be centered.

Using the remaining A, B and C squares, make a total of 144 combination-square-triangles. Pin the similar fabric groups together.
