I am thinking about doing this Link image here.
I crocheted a test granny square that was 3X3 wide and realized if I made Link all out of those squares, this would measure 7'X13'. Yikes! Way too big. I'm experimenting with using single crochet for this project where 5 sc is one pixel. After making a swatch of sc, I calculated out the project to be around 5' by 3'. Much better.
I'm going to buy the rest of my yarn today.
