While I had the Angelina handy, I tried fusing some to Bounce dryer sheets, to get a sort of transparent shimmery stuff. I also fused some Angelina to bright hand-dyed fabric, along with some silk sari ribbon that has a silver center. I used Bo-Nash powder to fuse all this to the fabric. These might make good postcard backgrounds.
Then I remembered my vow to do all the sample projects in Vikki Pignatelli's book Quilting by Improvisation, and went to the section on improvising blocks. This time I used a light stabilizer by Sulky, and made improvisational log cabins. You just cut the strips for each round in a funky manner, iron under the edge that will cover the previous round, and stitch down with an invisible zigzag or blanket stitch. I got two of these done. I used darks on the center and outer layers, and light or bright greens on the second layer. This might look kind of woodsy if I ever finish enough to make a quilt.
