Paper piecing. I believe every paper crafter has done it at some time or another. I know quilters also do a version of fabric piecing but I'm not sure if that is the right name for it. I've done this type of craft for many years but I called it "cut and paste". I didn't know there was an official name for it.
Recently I saw some cute pictures in a t-shirt iron on book and thought they would make cute images for gift tags. I copied the image on different colored paper and cut and pasted and voila...very simple, handmade, cute and fun.
