I was excited to receive this die but have been disappointed with its usability. To wit: the die cuts/perforates instead of just scoring. That means when I start folding, and especially when it's time to manipulate the circle into the rosette, bits start to separate, just like postage stamps (the old ones, anyway!).
The problem is not quite so pronounced on cardstock, but I'd planned to make rosettes from my stash of various printed mid-weight paper.
Sizzix customer service and a number of designers working for/with Tim Holtz say to just use Holtz's tissue tape or clear tape on one side of the rosette to ensure the little segments hold together. I don't always want to cover the print with another design element, though.
I have tried using two layers of paper--one slightly heavy, the other the one I really want to bend, and that helps a little, so long as I am precise in lining up the paper strips. This being a sizzlit die, it can't handle too many layers.
I supposed this is all still easier than scoring every 1/8 of inch by hand...though it is not as easy as advertised and I would hesitate to recommend it.
