Hi, are you rolling your g/p thin. You have to. Then press the cutter part onto the g/p. Twist it just a little. The petal should come up with the cutter when you lift it up. Then position it over the veiner , then press down plunger to create the veining. Lilft up ejector and press plunger to realise the flower. I had to do this several times with any of them to get the hang of it. I have used other hydrangea cutters, but not with the plunger. PME makes them also, i think. But just do as i have said(might take a time or two, Then you will get the hang of it. Good Luck. Rolling the g/p thin is the key to it.
