I'm a demo, so I'm biased.
I LOVE THEM!!!
I use a post-it to hold the framelit in place over the stamped image. I have a tremor in my hands, but can still manage to line things up. Beautiful!
OF course, because of the tremor, I'm TERRIBLE at fussy cutting ... so these let me do fun things like 3D ornaments without having them look like a Gr 1 student cut them!
Here's a simple card I did ... with the framelits and paper piercing.

Did I mention I love the piercing template! So many options ... with the framelits, with the stamps, without the stamps or framelits ... plus it matches the label framelits as well!
Yeah ... addicted to framelits am I!
