We saw them at a county fair or home show a number of years ago. Kind of interesting. My wife thought it would be fun to make some gift items for friends.
We bought the medium set they were offering and a bunch of accessory stamped rosettes, candle holders, etc along with 3-4 packages of flat stock.
She made one thing and it has sat idle since. Hoping to get back into it when time permits. Life just gets in the way.
It seems pretty decent for home-grown small stuff. I wouldn't build a fence with it. I thought it was a tad pricey.
