I just sent Irene a PM and will offer up the idea to the whole group. Since many of us have fabrics in what we consider medium range (and, yes it all depends what you pair it with to get contrast) how about we do some swapping?? ((I love swapping fabric!!))
I realize we're probably making our HST's using different techniques. Me? I'm using a 6" square of each light/dark.
What is everyone else doing? That would make a difference.
