I did a web search and found pictures of the quilts that won in Houston.
Mega-winner Sharon Schamber lives here in Arizona, so she teaches at several seminars around the state. She's a very down-to-earth teacher and unassuming, so her classes are laid-back and almost relaxing (compared to other teachers who often stress me out.) Last July she taught at Quilt Camp in the Pines (northern Arizona) and let us fondle her quilts, including her "Spirit of Mother Earth." She said she had entered it in the Houston show but wasn't sure it would even be accepted. (say whut?)
She hand-dyed the fabrics used in the quilt and spent 14-hour days quilting it on her long-arm machine. Her devoted(!) husband takes care of all the household chores, schedules her classes, and brings her food while she quilts. Even with that kind of help I still don't think I could quilt that many hours a day! She also said she's tired of competing. 8^)
