Here is my setup Gulp Bag $20, three accordion style folders (feathers, synthetics, and fur) $2 a piece, two flat plastic tackle boxes (came with bag) 1 for hooks 1 for Montana tying company bodies thread and tube fly supplies, one small accordion folder (hooks in zipper packs, beads, cones, and chain), and a 3 piece Cover Girl bag set for my eggs(stole from wife). Total cost no more than $30! I carry two vices one for tubes and a rotary (I usually end up teaching someone to tie) both are clamp style, but I carry a weighted base- you never know (reinforced from the article from Al Beatty) As you can see the front pocket is for my “work in Progress” flies or whatever I am too lazy to put away. The back has a mesh pocket perfect for a book and a few Hatches Mags Now I have a load of stuff and would probably need two of these to hold it all. If I just carry the things that I make 90% of my flies with then this does perfect!
Probably the best thing I found was those folders- Big Lots best price.
