This is one of my favourite tools. It is a simple and easy silicone flower veiner and used together with small 5-petal flower cutters it makes beautiful little sugar flowers.
The flower cutters I use most with it is: 5-petal (Orchard Products) and Petunia flowers(Tinkertech Two). When I make the sugar flowers I use sugar paste with a little CMC to make it hold its form when drying. You can buy the flower veiner here, the petunia cutter here and here.
Note: There are two different sizes of the petunia cutter by Tinkertech Two that is best to use with the silicone veiner.
