I typically prefer to use a tacky crafting glue when making craft projects with kids (either in clear, or original white)... If you would like to cut down on how messy this project can get with little ones, crafting glue dots work too. However, if older kids, teens, or adults are making this craft then hot glue (either low or high temp...both work) is a good option for glue, and can be used to speed up the crafting process quite a bit.
