I have also bought scraps here on the board, sometimes just for paying the postage. And there are very generous board members who sometimes have gifted me scraps totally free.
These wonderful members have done a lot to keep me able to make and gift comfort quilts which is my quilting passion.
I do also shop thrift stores; love finding almost new XL and larger scrub tops as they often are fun prints that are great for children's comfort quilts.
