I was first introduced to MISTI at the Bella Crafts Connection event at the Mall of America. There were several crafters in a class I signed up for that were using it. MISTI stands for Most Incredible Stamp Tool Invented.
They were a part of the Hot New Products at CHA 2016
This tool makes lining up your stamped images a breeze. If you need to re-stamp an image because the first pass did not turn out very clear, it will keep everything perfectly lined up!
