I've read a lot of tips and techniques on the forum, in FSM and on various other web sites and I think I have a couple tips that I haven't seen yet, though doesn't mean they're not out there somewhere already.
A friend of ours is into acupuncture, educated in and practices it. So I got a few of his acupuncture needles from him. They are very small about the same size as a .25mm dia wire (smaller than most sewing needles) but rigid and still flexible, they also have a very fine, sharp tip and a fore-finger and thumb hold on the end that makes them easy to handle. So far they have been great for marking a start point for the smallest drill bits and as an applicator for applying tiny drops of cyanoacrylate to the smallest spots. And I'm sure there are many other uses for them i haven't discovered yet.
I've read that many modelers use the foil from a champagne bottle for straps canvas tarps, etc. I've also found that the small metal container that holds tea lites is excellent for this as well. Tea lites are those small, white wax candles that many use to heat their pot-pourri pots etc. They come in bags of 30-50 and usually only cost $3-5.00 a bag. The metal is very thin and workable, easy to cut with a scissors or hobby knife. The holders are also excellent paint cups for enamel and oil paints and washes.
Hope this is helpful.
