I've held off sharing this quilt hoping I'd find out more about the maker and design, but several weeks have gone by and I've learned nothing, so since it was something I used stashed fabric on, and counted in May's Fabric Usage, I figured I might as well go ahead and share it.
The quilt top was rescued off the Seattle MQG retreat free table by Amber @greenamberdawn, then longarm quilted by Jana @janalroyal. Besides to these two guild members, credit also goes to guild Giving Quilt chair Linda Teri, who passed the quilt off to me for binding, suggesting "contrast would be good."
Perfect! I was free to choose binding fabric from my own stash, and used a fun pink on pink dot to finish the quilt, which measured 60" x 72". I'll return the quilt to Linda at our June meeting for labeling and donating. This year, the guild is donating to Kenmore Senior Women’s Shelter, YWCA Pathways for Women, and Westside Baby, so the quilt will go to one of those organizations. Glad I could help make it happen.
ETA: THANK YOU to Wanda @exuberantcolor for identifying the quilt pattern for me! It's Pixie Stix from Strip Your Stash by Gudrun Erla @gedesignsgudrun. Whew. One piece of the puzzle solved.
