I ironed one of Amy Mickey's transfers on to two fleece items: A micro-fleece vest and a fuzzier fleece (unlined) jacket. Both turned out great!!! Images are very clear and, so far, are adhering! The images are smaller ones that I put on the upper left front to the left of the zippers. Even it they don't stay on forever, they surely will at least for this trip!
ETA: Meant to add that since the fleece was a poly blend on one and poly on the other that I used a wool setting on the iron and ironed for 3 minutes (instead of on high for half that time).
