I love adhesive rollers, but sometimes they just don't do the trick for small embellishments. Sometimes, you also need something that's stronger than a roll-on adhesive. I kept running into this problem when tyring to attach "awkward" embellishments such as buttons or metal pieces. Granted, you can buy special glues/adhesives for metal embellishments, but Zots work surprisingly well on these items too (and they are less expensive). They also seem to hold better than regular "flat" adhesives. I've found the solution to adhering my small embellishments, and I've fallen in love with Zots.
