Disney Castle color-change tumblers

I have been playing with ideas for my craft fair booth and wanted to try some samples of vinyl I received in the mail, so these new color-changing tumblers from Michael's were the perfect opportunity to play.  I used silver rain holographic vinyl for the fireworks and Minnie's bow, and glitter rainbow vinyl for the castles.  I love the effect of the holographic vinyl.  Now, I have to put these through their paces and see how it holds up to washing.  Thanks for looking!  April
