Yup, Bridgend. Thanks, guys!
H2B told me about Hobbycraft, but I could have sworn that I saw something a bit closer. Then again, we've been driving around quite a lot-- it could have been more in West Wales, than South. Hm...
On the other hand, I still haven't really adjusted to the mapscale, here. Newport looks like it's 2 hours away, but chances are, it's only an hour...
