1) Aleene's Tack it Over and Over - You can buy this at Michaels for about $4 US, and if you use your 40% off one item coupon for these stores even cheaper!! For oversees I am not completely sure of where you can buy it in local stores, but I did see it for sale at A Cherry On Top for $2.99 US
2) Sheet of sticker paper (keep your old sticker paper once you are done with your stickers) you can use the paper over and over. Keep all sizes, or just one big one, up to you. ****do not use wax paper it does not work***
2) Place small dots on the shiny side of the sticker paper (the side the stickers were stuck to before you peeled them off). Make all sizes (the large dot on my paper is the size of a quarter). Small dots, medium, tiny, have fun with it!! Having different size dots gives you more flexibility in use when you need them. The big dots can blob out as you see in the next pic.
Make sure you store these dots with another sticker sheet on top or everything will stick to them (this is why I like to fold my sticker sheets in half).
One bottle of the glue will last you a long time. I have made over 1000 dots, and I still have half my bottle left!!!
These homemade glue dots are better than the ones you buy!!
