"I used my stkr it in my hand made birthday cards. I am the Grandma of Quads (loving known to me as The Quad Squad). They turned 1 this year. I created birthday cards for each one of them and applied stkr.it to each card. So much fun and so very different. These are now keepsakes for all four of them to look back on as well as listen to. Love, love, love this product!!!!" Thanks for making this such a fun and easy product to use!!"
