Finding my soldering gun is easy, but I'd always have to dig around for the solder. Here's a quick and simple way to insure you have everything you need at the work space, whenever you pick your soldering gun up to use.
Step 1: Materials
Besides a soldering gun (Mine's a Weller, but I'm sure you can modify this to work with other guns as well) a sewing bobbin, a 1-5/8" drywall screw, a philips screwdriver and about a foot of solder.
The most difficult part of this project will be distracting your wife long enough to get the bobbin. My method was to point at something behind her and say "What's that?", but you can use any technique you'd like, including taking her out to dinner.
