What size cutter do you use for lifelike size roses for on top of a cake? they have them from 110mm- 30mm...confused.

For roses that go on the cake top, I like the 100 and 110 size. For me, the 80 and 90 size roses seem too small for the top, unless you are making a rose ball with a lot of roses. I like them better on the tier ledges.

I agree, if they are the only thing on the top I would go with the 110m size.

The 110mm come out big enough that you don't have to make a lot of them.

The best thing to do is get at least two cutters...say 100 mm and 110 mm. Use the 100 mm for the inner layers and the 110 mm for the outer layers. You can do it with one size, but you end up needing to stretch the petals a lot on the outer layers.

Here are some made with the 110mm.

And these were made with different sizes.
