Am thinking of having a go at making a large-ish wooden frame for a
print that She's just bought... can't believe the cost that she was
quoted to have it supplied framed.

I was thinking of buying some lengths of moulding from Wickes, mitring
the ends and sticking them together. Is that about it? My main concern
is getting the thing square - presumably the pros have special
jigs/cramps for this. Can it be done effectively in two stages. ie
gluing diagonal corners, letting them set, then doing the other two?

Any tips or experience welcomed!
