Quilting fabrics are available online at literally thousands of websites. An experienced quilter will do most of their shopping on the Internet, where you can comparison shop from the comfort of your living room, rather than going from store to store! Quilting supply retailers will often extend discounts to their online customers, so pay attention to the sales as you let your fingers do the shopping!
When choosing quilting fabric, be sure to select only one type per quilt, as not all fabrics wear in the same way, and a heavier fabric can stretch or tear a lighter one such as cotton. It is best to use one fabric type, unless you are making a crazy quilt. Broadcloth is probably the most popular type of cotton fabric used today and tends to be relatively inexpensive, with a wide ranging color palette and print availability. Another popular type of quilt fabric is batik, which is cotton that is dyed in the batik style, making for rich, deep true colors that do not run or fade with washing. Batik will generally cost more than plain cotton broadcloth, but makes for a striking addition to any quilt.
