This past weekend, I was in the mood to just play in my studio, so I did something I've been wanting to try. I painted Wonder-Under! It was fast and fun and only slightly messy. I painted one side of Wonder-under with watered down acrylic paint, spreading it around and blending colors right on the surface of the W-U as I went. Once it dried, I cut shapes out of it (paper and all) and ironed them to a piece of fabric I'd dyed some time ago. The stripes just appear as the W-U dries and shrinks up a bit, causing the backing paper to wrinkle a bit.
The effect was quite different than I thought it'd be. Once I peeled up the W-U backing paper (which was far easier when the shapes had cooled completely), the colors were vibrant. And there's no sticky residue at all. I just have to remember not to iron this with some parchment paper over the top.
Stitching was fun and free and kept me going through the closing ceremonies of the Olympics.
Hmmm, I'm going to have to play more with this. By the way, I've not come up with a name for this yet, so if you have any suggestions, I'd love to hear them!
