The ordinary yo-yos work well and fast. I've used the heart template with much success. There is, as with everything, a bit of a trick and you actually have to shape it by pulling this and that way and also sometimes use a pin to tame the folds. The flower is a bit finicky and I perfer to use other methods for flowers. I can't wait to get hold of the butterly one and the oval one, but they are not available here yet. DFon't sell yet, give it another go..
