-Don’t touch the metal part. This is a duh. But important.
-When you’re project’s finished, get rid of those pesky glue strings by blow-drying your project with your hair dryer (use a low-heat setting). Just don’t heat it too long, or you’ll weaken your craft.
-When gluing thin pieces of fabric together, don’t press with your fingers -- you might burn yourself.
-When you put your hot glue gun down, it will drip bits of glue. So don’t set it over something important. Try setting it on scrap poster board or foam board, or an old placemat.
-Keep a bowl of cool water nearby, just in case you do burn yourself.
-Hot glue is great for decorative and jewelry projects, but it isn’t the most durable or adhesive glue out there. If it gets too hot, it will weaken again. You can find extra-strength hot glue at some craft stores, but hot glue isn't the answer to all of your adhesive prayers (looking to stick some glass to some metal? How about some plastic to some wood? Try E-6000 instead).
-This means you shouldn't use hot glue to fix the bottom of your shoe, a broken coffee mug handle, or that little rhinestone that fell off of you kitty's collar.
