I use the pinking blade for fleece appliques (fleece on fleece). I also use the patented "skip-stitch" blade for poking holes in fleece for crocheted borders. They come in three different sizes (holes and distance between holes) and are available at skip-stitch.com. The fit on standard Olfa and Fiskars handles. For me, I find the pinking blade dulls quickly, and that may be due to the nature of the pinking design, plus the fact that fleece is hard on cutting blades. The skip-stitch blade lasts a long time, and I use it a lot for Project Linus.
