Thanks, Grunger. I have no dressmaking skills whatseover, so I will be impressed with whatever you make from your length of tartan. You mentioned a waistcoat, that could be lovely.
Jigjag's jeans problem was ... choice. There seemed to be too much of it! I think the terminology threw us too - Marks and Spencer seemed to have strings of words to define the jeans. I've just had a quick look at their website and that seems to be still the case.
Jigjag, good luck with any jeans hunt - rather you than me!
