Thanks, ladies!
I did a memory quilt "nap quilt" for her mum last year and did it all in pinwheels. It turned out great, but to find pieces of fabric big enough for pinwheels was tough. And I'm using some of the clothes left over from that.
Joanie...I know for just string quilt I wouldn't need to, but with the addition of stretchy fabrics, I was nervous. Getting the stretchy to lay down on the muslin and get sewn to the "not stretchy" will be difficult...should I expect problems when I quilt? If it's floating like that, without a stabilizer?
