Ever had a eleventy billion hair ties lying around your bathroom? I did. Not sure how it came to me, but it's super simple.
This roll fits the tiny ones and double over the big ones and it fits them too! It's perfect!
First, cut more or less straight lines in all but one toilet paper roll and stack them into each curler them tighter and tighter.
Until it looks like this.
Put a little tape at both ends just to make it hold together a little better. And cut plenty of paper to cover the roll. I'd roll with the curl of the paper, it looks better.
Secure the paper seem with clear tape, the whole length, otherwise bands can catch on it and tear. Start folding the paper in. Take it in triangle sections so it's rounded.
Another variation not shown, you can twist the ends out like a tootsie roll and secure it with ribbon, make it look like candy! :)
Ends should look like this. Secure with dots of glue beneath the folds.
