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.
Step 2: Assembly
Looking at the picture, you'll understand exactly what needs to be done. simply remove the forward assembly screw from the gun's case and replace it with the drywall screw and bobbin. Wind your solder onto the bobbin and your done.
Step 3: Use
You don't have to cut the solder off the bobbin when you use it. Simply unwind enough to reach the work and solder away. The solder is stiff enough to keep itself near the tip while your preparing to heat the work up, so you don't even have to reach far to access it.
