Dark (color #1)
2 - 2" x 19"
Light(s) (color #2 & #3)
1- 2" x 19"
Sew a light strip to each of the dark strips. Press toward the dark. Check to make sure your strip sets measure 3 1/2". If not, you need to adjust your seam allowance. Look how well this book (that was placed there by my little helper before I could snap the picture) matches my fabric.
Lay the strips sets right sides together locking the seams together. The dark colors should be opposites.
Use your easy angle and cut 8 "pairs" of triangles. You should have 4 of each "kind". Leave the triangle sets nestled together and sew.
Press the units to one side. Join the 3 1/2" squares (4 of each kind) to complete the blocks. The light will be dominant in one block and the dark in the other block.
This is a really fun block to make with your Jelly flops. You would do it the same way with a light and a dark. In case you are wondering- I am still loving my fireflies. This block would be great for a charity quilt as it goes together quickly and the block has a lot of movement.
