Made my own homemade fly box today. Went to michael's and bought a bead container. It had 4 large compartments and 4 small, which i put magnetic strips in, and I glued foam to the upper half. Now i have compartments for splitshot, streamers, or tiny flies, and a foam insert for dry flies. It is all in a 3.5" X 4.5" container. Perfect for my vest.
