I generally use only 100% cotton because I like the feel of it. I was recently given a very large bag of poly cotton fabrics in lovely colors. They were given to go into charity quilts. I am sure they will be very well recieved.
I have often been asked if I am a quilter and asked for advice....but then I carry quilted purses. In my county, I am often asked by strangers to explain a quilting process or design. The last time I was in Walmart, someone got out of line to come over and rave over my purse. I guess i just have a friendly face.
