It was tough finding enough free patterns to make this project page but I think these will do the trick, there’s a nice variety here. You can sew zipped pouches to use for the fanny packs or use a ready-made one and carry on with the methods outlined in the tutorial. Most of these are sewing projects but there is one knitting pattern and one no-sew project. If I find anything new (original), I’ll add it to this list. I included a wrist pack and a runner’s belt since they function in a similar way but on a smaller scale (and they’re useful too). Enjoy!
DIY Waist Bag : A ready-made zipped pouch of your choosing (make-up bag, pencil case, etc.), is transformed into a fanny pack by adding ribbon, chain and a carabiner (no-sew, uses a glue-gun).
The Hipslinger : A pouch (with foldover flap) is sewn then attached to a fabric waistband that has velcro & carabiner clips on each end.
Wrist Fanny Pack : A length of ribbon is sewn to a zipper then snaps or velcro are added to the ends. Large enough to hold a stash of cash or a key or two.
