Has anyone ever used the wilton icing sheets to cover a half sheet cake instead of fondant? Any thoughts on this? thanks for your time.

I wouldn't do it.

The sheets don't have anywhere near the flexibility of fondant.

They're great for flat or gently curved applications.

You can wrap them around a cake or apply them to the entire top, but you really can't mold them over an edge without them cracking or breaking.

I agree with BlakesCakes, they are stiff and drier --you may have some luck but I just tried to have my son use it on a half ball pan, and the decal we made was a little too dry to conform to the spherical shape.

I had a student last night cut strips out of the sugar sheets and had them go from the bottom edge of the cake all the way up over the edge and to the middle. She did not have any breaking with them at all.

what about cutting through it when they go to cut through the cake with a knife. Does it cut ok?
