So this is as far as I have gotten on the challenge block. This photo shows a more "cheddary" color than the actual fabrics. These sqaures are 1 1/2 " so I'll need 144 total. I'm not sure where this is going, but I am having fun so far. Oh and this it the first time I have ever posted on a blog. I hope I did it right!
