I am attaching some pictures of my summer challenge project.
First, I cut colored strips from scraps. I made these primarily dark or medium strips. The red center blocks were cut from a fat quarter I picked up somewhere along the way. Then I cut the beige strips from some fabric I had left over from another quilt (I bought much more than I needed.)
Then I put the colored strips in a bag according to their size and pulled out strips randomly as I needed them. I kept it random unless there would be two of the same design in the same block.
I laid out the blocks in many arrangements on the living room floor and then decided on the zigzag arrangement because it reminded me of waves.
There are six 8 inch blocks in a row and 10 rows. I am putting a narrow black border around the arrangement because I think I will use this as a wall hanging.
