Here are my Stillwater fly box and four streamer fly boxes. In the past I only had one streamer fly box and had all my other streamers stuffed in a standby box, but this year I bought four of those plastic boxes (look just like the Cliff Bugger Boxes) from JoAnnes for something like $6 apiece and then used the spray adhesive to fix 4mm foam to the insides.
