Once you start using eyelets and see the effects they have on things (cards, scrapbook pages, etc), you won't want to stop!!!!
The options are endless! Explore! Experiment! and most of all, HAVE FUN!!!
Since I started using eyelets a couple of years ago, I've been looking for more and more types of them (Stars, flowers, squares, angels, Christmas trees, stockings, snowmen, turkeys, pumpkins, leaves, and of course I have lots of colors of the regular round eyelets).
You need a hammer, eyelet setter and a hole punch as mentioned already.
I have the eyelet setter and hole punch set from Stampin up...though they work they are NOT the best.
My sister ordered a set from QVC and the set she got was MUCH better. However, she also, later, got the set from Michaels.
I now have the hole punch that she got with her set from QVC because she liked the punch from Michaels better. And she gave me the setter that she got with the set from Michaels because it is better than the one from Stampin Up, yet not as good as the one from QVC.
I'm not recommending that you buy both the set from QVC and the set from Michaels, but I'm telling you that the best punch I've used is the one from Michaels; the best setter is the one from QVC and ANY SMALL hammer will work (I happen to have the one that came in the set from Michaels because my sister kept the one she got from QVC).
The self healing mat is WONDERFUL...just make sure you don't use the back side of it...the back side does NOT heal!
