Hanging on the quilt rack in my miniature quilting studio is this tiny Sunbonnet Sue quilt, which is about 5" by 6". It looks so real for such a tiny scale-- it's actually made with a photocopier technique!
Gail, an acquaintance, made several tops using fabric a photograph, and a photocopier (couldn't say exactly how!) and taught a class on finishing the tiny quilts. I love how she got the lines and color so crisp! We backed them with a very small-scale print, hand quilted, then bound them by hand. I seem to remember that we used white cotton flannel for the batting--it seems to be just the right weight. It's perfect hanging in the little sewing room!
