a review of adhesives used by actual scrappers...and a lot more!
These are not dots, but sheets of adhesive. You peel the backing off and rub the adhesive on your vellum. I didn't feel like it stuck as strongly as I would have liked. I think that the ThermOWeb adhesive runner sticks better.
Please see the example of the adhesive with vellum on dark and white paper. The invisibility is excellent.
