I had NEVER heard of this! I ordered a Christmas packet a while back & once we tried it - we were hooked! There's also animal packets, princesses, space, dinosaurs, unicorns, & more! This would be a great activity for colder months (I know we will be doing it!) 🌟 TIPS •Be sure to press down everywhere on the foil sheet once it's covered the sticker. We pushed down with our full hand and then used our finger to run it all over the sticker in order to get the best coverage. •Foil sheets can get multiple uses. If you use one to only color a small section of sticker, save it & use up the rest on another small area. •Recommended for ages 4+ (and I'd agree with that) LTKkids LTKHoliday LTKfamily
