Making things out of duct tape is such a Poindexter thing to do. But there are so many nice colors and patterns of the stuff how there, how long can you resist?
I made this little thing by tracing an "Extra Gum" packet onto duct tape 'fabric'. The gum pack closes with that tab, but I don't have a utility knife handy so I punched a whole in the tab. Right now I'm just tying it shut with yarn, but I might figure out something better to do.
There are a lot of places to learn how to make duct tape wallets and more. I think you could use this particular idea (probably not original, but original to me!) for a cute little sewing kit. Or maybe you could find a pad to fit inside it and some mini gel pens? I think it would make a cute stocking stuffer!
