I began working in a quilt shop three years ago. Have I learned a lot. One thing is to always purchase quality fabric. Some quality fabric manufacturers are Hoffman, Kaufman, South Seas, Benartex, and others found in quilt stores. I gave away all my fabric that I had purchased from fabric chain stores. The quality is very different with higher thread count, better thread and better processing, thus a higher price, but well worth it.
Also, we always piece our quilt backs, often using the same fabric as in the quilt. Many of our quilters make a simple design from their scraps, and then the quilt is reversible.
