SDU (Scrapbooking Design & You) Classes is a powder tool. Sometimes when you want stickers to have more dimension than normal, you can use a 3 D Dot to make it stand out more, such as I did on this cute little owl sticker (Sticko, On the Farm). First, before I took the liner off of the 3D Dot, I used the powder tool to brush on the powder that makes the sticker not be sticky any more. That way, I don't have to worry about the sticker back catching on the paper behind the owl and making him look deformed. I also added some googly eyes to him as I felt he just needed them!
All of the EK Success Brands are now represented on the new website, http://www.eksuccessbrands.com/. The powder tool is one of those things you can find there that aren't as easy to find in retail stores since so many scrap booking stores have closed.
