Anyone know where to get plaster of paris molds?

[Maudy]

Or is it moulds?

I want them for DS1's birthday party and so want so boyish things ie: aliens, mosters, dragons etc. Can't seem to find them anywhere but to be honset I'm not really sure where to look.

How about browsing through the ads in the craft magazines in WHSmiths? Covertly take down the number of any promising looking companies, so you dont have to buy the mag! There's also a huge craft catalogue for sale, but I cant remember the name at the mo. I bet they'd have something in there. Or how about kits from toy shops... do Galt do anything like that?

think there are some in baker ross catalogue

I've looked in Argos and Toys R Us but they only have Thomas the Tank Engine and Noddy which is a bit young for DS who will be 7.

Like the idea of checking mags though! Thought of trying art shops, do you think they will have them?

Have a look here and search under plaster. If you scroll a few pages (past Disney Princess, Thomas and Bob!) there are dinosaurs, planets etc which can be fridge magnets and so on.
