These are the easiest rolled paper beads you'll ever make.
There's no template required for these.
Just cut strips and start rolling. The longer/thicker the strips the bigger the bead could be. Experiment with different size strips and different size tools.
As with all paper beads, you can coat them with sealer to use for various projects, and to make them last longer.
I use a variety of things from wood hardener (from the hardware store) to Triple Thick (get that from Amazon). Try a few different things and decide what you like best. You can get a bunch of different varnishes from the craft store too.
