A cardboard tube such as is I the center of a roll of paper towels (or toilet paper) works much better, but it's garbage day, and the recycling has already been picked up, so I needed something better. Enter the ubiquitous Altoids tin. I can never seem to toss them in the recycling bin, they're just so handy! So, there's usually an empty one floating around my house.
I simply inserted one end into the tin, closed it, and wound the bias tape around it, then secured with a pin.
I like that it isn't going to crease my hard-earned bias tape, and I like that I can stack them in my sewing closet a little better than rolls around tubes. Alright, I admit I also like it because it's an excuse to expanding my Altoids tin collection.
