[quote=luvspaper]I think it is www.paperpieces.com that sells them precut. They come in different sizes.
I use the ones from paperpieces all the time. They can be used several times. I also use the machine to baste each edge using a very long stitch. This speeds up the process and lets me spend more time actually putting the "flowers" together. Tweezers work well to pull out the basting threads.
