I want to start practicing making fondant/gumpaste flowers/designs. I have seen a couple of different types of gutters on the web. i.e. plunger.

What would be the best type for me to purchase?

To get the most bang for your buck, try the Wilton set or one of the JEM sets.

I tried the JEM cutters and could not get them to work at all. The gumpaste stuck in the cutters and by the time I got the flower out it was dried and distorted. I used the PME plunger cutters for mine and they turned out great!
