What sort of varnish to seal acrylic paint?

[lucysmam]

Or rather, to protect it?

I've been busily painting spoon props for work but haven't varnished them yet because I'm not entirely sure what I need.

They're cute. If I want to protect any wooden projects I usually use a 'yacht' varnish, matt. It's pretty long lasting too.

Thanks @WoozieFloozie, I'm not sure where to buy that so will have a google now. Much appreciated :)
