Quilts are a uniquely American art form, and quilting has become hugely popular in recent years. Wonderful heirloom quilts that used to be common flea market fodder are now gracing the walls of art galleries across the country. That crazy quilt your gran used to drape across the back of her sofa could be worth a bundle. Its vivid velvets and cunning decorative stitches, stylish cobweb motifs and vintage buttons might also be the stuff you dreamed on during childhood naps. If you've ever dressed up in a quilt and imagined yourself a queen with a royal cape to match, that imagination-inspiring quilt is priceless to you, regardless of what it's worth on the open market.
