I just did an embroidery design on a single layer of fleece that is a pattern piece for the front of a child's robe. I used a heavy tear away on the bottom and basted the fleece as the first step of the embroidery. I had no stretching at all. The fleece wasn't in my hoop, just laying on the stabilizer which was hooped. I was afraid hooping the fleece would make marks on the fabric. Everything worked wonderfully well. The design had 14,500 stitches. I used my large hoop but the design was just under 6 inches square.
