I recently had a custom order for a tooth pouch. The customer requested a rainbow tooth pouch with out a face on the tooth. Of course I could not find any felt with rainbow print so I improvised and pieced the colors together.
I was really pleased with how it turned out. You can now purchase one for you little tooth wiggler from the Etsy shop. They are not limited to Rainbow colors. You can choose 2, 3 or 6 colors. They will be alternated or they could even be done in larger stripes.
