Hot glue gun and sticks

Hot glue guns are handy for so many things.  In addition to foam construction and repair, they turn out to be handy for all kinds of crafts and household apps.  Who knew!  You will need a model that supports high and low temperature settings.  FYI, that's 230 and 380 degrees F.  Get one with a base.  They all say theyr'e drip-proof, but they all drip.  The base has a countersunk hole for attaching it to something heavy; I've been thinking of doing that.

If you've got a hot glue gun, you'll be needing some hot glue sticks.  This is a nice big package for a pretty good price.  It's food-safe, in case you were thinking of gluing your food together.
