I use Marianne Creatables Dies for my poinsettias. She has three sets to choose from, or mix and match if you like.
I have
THIS ONE. And
HERE IS A CARD that I made with it so you can get an idea of the size. I like that you also get a little stamen to go in the center of the poinsettia.
THIS ONE is the same size but with serated edges.
And
THIS SET, which I've not noticed before is a mini version of the two previously mentioned, all in one set.
I'm off to check out what else is new with Marianne. ;)
