I don't have much to trade that you guys don't already have, so I like the idea of making something new. It'd have to be something a bit cack-handed and feckless, but still - it's the thought (or the quiet desperation to get my hands on one of these) that counts. I could do the mobile photos. Otherwise, it's t-shirts or pottery, and then we're into the world of craft fairs and paperweights.
I have a pretty good recipe for brownies.
Since everyone else has bagsied a number: I was born in '77, the year genetic engineering gave the world recombinant insulin produced in bacteria, which could only previously be gotten by slaughtering pigs and cows for their pancreas. Failing that then anything prime would be good.
