Got a couple to buy for whose hobby is buying junk tat nice antiquey type things, polishing them up a bit or restoring them in some way, and then reselling at vintage fairs / markets etc. They're pretty good at it. Relatively small scale: largest thing they've done is probably a table, they like odd bits and pieces rather than massive projects.
Any ideas of anything related I can get them for Christmas? Only a £15 budget 
limiting I know. So far my only idea is a set of touch up wood pens, which doesn't exactly challenge the budget.
They've given us some lovely home made hampers in the past, full of pickles/preserves etc, just to give you more of an idea what they like to give/get.
