This glue is great. I have tried to put glitter, foil, gilding flakes onto my stamped images using a a couple of different glue pads, an embossing powder which goes sticky when heated and size. Some sticks, but I have never got a detailed image. I bought the following glue at the NEC and the first time I used it I got a brilliant detailed image. Can't wait to use more of my stamps with it. It is water based and you do need to wash your stamps immediately, but will work with clear as well as rubber stamps. It can be used on coated & non coated cardstock, acetate, vellum, wood and material (haven't tried any of these yet!). You just use cut n dry foam to create a small 'ink pad' with the glue and when stamped wait for a couple of minutes for it to go tacky. Apparently you can return to it any time and it will still be sticky.
This is the link and it works out under £6 inc p&P and I should think it would last ages. You will need to scroll down to the bottom of the page to find the Flitter Glu.
Hope this helps anyone who has also tried these sticky pads without success.
