At least 3 yards. In our Quilt Guild we freqently trade fabric with one another. We all shop at the same stores (we go on road trips to fabric shops). The same fabric appears in almost all of our quilts. The only difference is usually in our taste of patterns/colors and how we use it, so if trading an 1/8 of a yard will give someone else's quilt just a little punch on a block or two, we happily accommodate. We are all very generous about sharing fabric, patterns, thread, templates, and time. But that is what makes the group so enjoyable. Actually it is a lot like this group. Everyone is so generous about sharing their knowledge and information. I always look forward to receiving a notice from this group. I would like to thank all of you for making this a fun place to be.
