Here are a few more resources that I have noticed in the past few weeks that may be of interest:
Entering Shows - Elizabeth Barton had a great blog post on May 3 with thoughts on entering shows. She discusses both the value of shows and deciding which to enter.
Displaying a small project - J Bryant Campbell had a great post on April 26 on mounting a small fiber piece. It would work well for small art quilts. Her photos really help explain the process which she has used many times.
Three Techniques for Binding - Susan Knapp had a blog recently on finishing an art quilt with a non-mitered facing. She provided pdfs for the instructions as well as a mitered facing and a pillow case style.
