I'm with Onebyone. During the many years I was able to hand quilt, the very best hoop I found was one that tilted and swiveled on a base in my lap. It was so much easier not to have to support the whole weight of the hooped quilt with my hand/wrist/arm. Mine is made by Grace, but is the same principle as the one pictured in Onebyone's post.
