Eva asked about the technique of folding the backing over the top of the quilt and hemming it to finish a quilt. It is probably not the best way since the edges get most of the wear and tear, but it is the way I have usually done it. It's also the way my grandmother, great-aunts, and great-grandmother did it. But after she asked, I started wondering about it.
I grew up with their quilts (and am lucky enough to still have some of them) but I did not learn how to quilt from them because I had moved away from home. I learned how to quilt by studying library books and then after I had made a couple, showed them the quilts. At first I only made tops and I paid one of my great-aunts to quilt them for me. She and my grandmother shared patterns and books and they gave me advice. In the first photo, "Grandmother's Fan" was one of the first quilts I made that was quilted by my great-aunt. I'm also particularly fond of it because I worked on it during a trip through Europe (England, France and Germany).
One of the books that I did own and study was Polly Prindle's Book of American Patchwork Quilts by Alice Gammell. It was first published in 1973 and I have the 1982 copy. According to this book, the usual procedure is to attach a binding, however, it does state: "If your quilt has a sashing and a separate edging is not desired, make your quilt back larger than the quilt top. Turn this extra material over the top, fold under 1/4 inch for the hem and hemstitch into place." (page 34)
