Well, I have to be mysterious for a few more days as I finish up some stitching lessons (there's one more hint, I suppose). It's been a wonderful experience, and I love stitching up these little hoops to track my progress.
My "fabric" is a blue men's dress shirt I picked up at the thrift store for 1 dollar. It looked new and is very large, so it's yielded plenty of space to stitch on. :)
More details on what I'm stitching for... soon on Feeling Stitchy! :)
