Humidifying Your Guitar

With the winter heating season on it's way (at least in the more northern climes), it's important to make sure your guitar does dry out due to lack of relative humidity in the air.

I've been using one of these home made humidifiers in each of my cases, they are cheap to make and work great.  They hold a fair amount of water, so don't need frequent refilling.  One tip, use a decent quality sponge, they are treated to prevent mold growth.
