Circle Zip Earbud Pouch | Erin Erickson

I’ve always been a bit scared of sewing in zippers - I’m terrified that it’s going to get caught in the foot of my sewing machine and break it! But this seems pretty easy to make, and of course you don’t have to make it for earbuds. Add it to your keys and keep some change in there for those times you get stuck at the parking meter, or add a clip to it and use it for adding your key to if you go out walking.
