You guys know those cheap little exacto knife type things for cutting around shapes and such?? The scrapping ones? Do they actually work well and can you use them on thin paper or just cardboard etc? I'm doing some zoo pages and just spent AGES trying to cut them with scissors. SO ANNOYING since it was supposed to be a simple lo. lol I don't have money for a cricut and that but maybe one of those would help? TIA!
