I tie my jigs when I need them. Which means on the water. I bought some small twosided boxes at Kmart that work great for jigs. I just throw them in the back of my vest. Same goes for spinners. The boxes were like a buck a piece. They have varying sizes. You said in one post that you use a stick for wading. When I know I will be up to my belly in water, I bring an old ski pole to use as a wading staff. The point digs in well and I can attach the handle to a string to allow it to flow behind me. But BEWARE of turning without it in hand. Trip, splash, and wet. A thrift store is a good place for those.
