So I found Hobby Lobby is carrying 'plastic cake boards' these days. They look like the wilton cardboard ones but all out of plastic. Much sturdier and washable and not that much more expensive then the cardboard ones.
I have been looking everywhere for one. Can't find it. Lowes & HD people say they don't carry it. Where did you get yours and how large a circle can it cut?
Question. How thick is standard foam core? Is it visible and should I cover it with icing?
