I use www.betterworldbooks.com
Its run by people who try to save books from landfills, etc and gets books to places in the world to promote literacy. If you go to the site you can read about how they started. They ship anything you buy for free, and they used to sell some of the stuff for 5 for 15$ but I see now they have books listed at 2 prices, new and used at 3.48$ a book.
I think you can sell books back to them, too, you used to anyway.
for quilt books you: click popular catagories, click home and garden, click crafts and hobbies, finally click quilts and quilting.
on the page that opens they have a book Id love (well, Id love a bunch of them!)- "The Prairie Girl's Guide to Life: How to Sew a Sampler Quilt & 49 Other Pioneer Projects for the Modern Girl" by Jennifer Worick. also, next page: "Quilter's Country Christmas: More Than 50 Projects to Make Your Home, Gifts, and Decorations Extra Special for the Holidays by Leslie Linsley. Id love that one too. Theyre both 3.48$ each, free shipping.
Im really bad about books, even worse than collecting fabric! sharet
