Is there an equivalent in the UK to Wilton's cake decorating courses? I've seen some courses offered at my nearest cake decorating supply shop but don't know where else to look.

AYou can do wilton courses in the uk or try pme.

There's classes all over the place, you just have to look a little harder for them than in the US.

Granted, they're a lot easier to find near London. But a Google search should find something near you. What county do you live in?
