While I was in Minnesota, I mentioned that I was thinking about buying a Xyron sticker maker. My 16-year-old brother Henry piped up and said "I still have Jake's old one that he left me. I never use it. You want it?" He got it out, and lo and behold, it's an older version of the Xyron 250, which they apparently used to bill as the "Magic Sticker Maker". All signs point to the fact that a Xyron 250 refill cartridge will fit in it. I'm very excited.
Here are some stickers I made out of some vintage wallpaper that I cut up:
And here's a fabric sticker (Ooooo, ahhhhh...)
If I were you, I would expect the amount of stickers produced to increase dramatically, and then I would expect to see them for sale in sets and in card-making kits on my Etsy shop. But that's just me.
