another thing I do sometimes is take aluminum tape* and wrap it around my finger tips leaving some extra at whatever part of my finger contacts the string. The tape is .005" thick, the backing is VERY sticky, so you can build it up pretty quickly to whatever thickness works for you. Because it's aluminum, you can trim it with regular scissors (but don't use your wife's quilting scissors. Don't ask how I know this is a bad idea)
the advantages of this approach:
1) the tape is widely available at "man" places like Home Depot, and you'll never need to venture into a nail salon to buy it

2) you can put the "pick" part pretty much wherever you want it (as opposed to most commercial finger picks which may not put the sweet spot at the location where you naturally contact the string
3) it goes on quickly and comes off afterwards, you don't need to wear it except when you're playing guitar
4) yet its sticky enough to stay on while you're using it, unlike some commercial fingerpicks which tend to slide off
disadvantages:
1) When people notice you're playing guitar with duct tape on your fingers, they'll make fun of you. (Again, don't ask how I know this.)
