Blind embossing doesn’t need ink or special tools. The idea is to cut shapes out of cardboard or use some string or other found objects and make an imprint of their texture. There is something very fun and unique about a subtle shape embossed in a piece of paper.
This technique is probably the most rewarding and easiest to do! We love using it at fairs and events, because people can make a print in literally 30 seconds. It’s great for kids, too! Just make sure that kids use the press under supervision only.
