Well, THAT was a fun rabbit trail to visit!
Cutting all my needed strips and squares for step 3 took about 45 minutes to do. Then the strips will make.... Wait for it.... Can you guess?.... That's right - 9 patches!
My quilting club leader loves the 9 patch. It's her favorite! My patches will be light scraps and purple scraps. 4 light and 5 purple in each one. When complete, they'll be 3-1/2" blocks. I don't remember how many I need to make but I'm sure it's a lot. After all, I'm making a quilt for a bed! I'll have to let you know when I'm done.
The white squares must be a prep for another part later. I have no idea what! It's a mystery! :)
