I know there is one in an old magazine of mine. Now I just need to find it! I did find a picture of a lego quilt online. Each lego block only had one connector button (I don't know what else to call it!). I want to make mine with 2 connector buttons per block, if that makes sense. The picture I saw was made of just 4 solid colors: red, blue, yellow and green. I'll keep you posted.
