We recommend using Zip Dry Glue for all your mounting needs. Zip Dry Glue sets in about 10 seconds to give you time to adjust, and center the piece. Only a small continuous bead (the thinnest glue line you can make) around the border of the piece is needed to be mounted. If you use to much glue it could seep through your paper & ruin your project. Practice first! Tips: When you cut the tip of the nozzle just clip enough for the smallest amount of glue to pass through. If any glue shows out from the edges, wait for it to dry, and it can simply be rubbed away with the friction of your finger tip. Zip Dry Glue should not crinkle or buckle the paper if the proper amount is used. Always recap your Zip-Dry Glue or it will dry up & you will have to re-cut the tip every time you use it.
