Eddie, thanks for the tutorial. It is very concise and to the point. I think almost anyone would be able to make a CW with your instructions.
I have worked on one by hand..I say worked on one because it is still about the size you see in my Avatar and that picture was taken several years ago.
I started my CW with a 9 in square...I am wondering...if I was to do a bed size, how big a square could I use and still have it look intricate?
