This one is the most basic. Plain white bags, plain stars, and the only other tools you need are some glue and a pair of scissors. You could dress these up by decorating them before assembly with markers, stickers, foil or any other way you can imagine to change plain white to something more exciting.
These are dressed up a little with colored bags, an extra snip (a bit like cutting a snowflakes) and a slightly different way of connecting the star once you have all the bags glued together. The only tool you need here that wasn't part of the last one is a brad for fastening the ends of the stars.
I'm including one more, not to show you the technique (it's the same), but to show how you can change the look by using fancier bags. In fact, you don't really have to even watch this one. Just look at the opening screen to see the result.
I've got some family gatherings coming up, and I really think this will dress up the party.
Have you ever tried this? If not, have fun!
