Here is what my kit looks like (The binder has a zipper that goes around three sides. The zipper will hold materials in place during transit, or in the event the kit gets dropped. It will also help keep materials safe from insects, while the kit is not being used.):
Outer flap opens and has pockets for pens / tools / Identification Card. I've added a couple Sharpie permanent markers, which are handy for some patterns.:
Unzip the binder and open it up. On the right-hand side is an expanding file section. On the left-hand side is a three ring binder (removable from case). I have added a plastic zipper pocket and multiple sheets for holding materials.
View down into the expanding folder section. Perfect for holding a few small capes/saddles/etc.
These necks/skins cover a range of patterns. The materials in the kit can easily be swapped out to suit the type of tying that I will be doing.
Large three-section pockets for holding hooks / etc.
Flim strip Negative holder sleeves are perfect for holding sections of longer materials (i.e. - pheasant tail/peacock herl/flash/zonker strips/etc.)
Overhead slide holders are perfect for holding small patches of fur, dubbing, carded silk, yarn, wool, ribbing material, etc.
The whole kit weights only a few pounds when it it full, and has a little bit of everything needed to tye a range of patterns (soft hackles/streamers/steelhead patterns/tube flies/etc.). It took me many hours to fill the binder with small bits of material, but hopefully it was time well spent. I have some other interchangable sheets that I can use to tye other patterns (foam patterns/dry flies/nymphs/ etc.).
One of the components that this kit does not contain is holders for wire, tinsel and thread. I don't like winding these materials onto the cards (it ruins these materials by forming kinks every time it wraps around the card). These materials would need to be carried separately from the tying kit. The tying vice/tools/bobbins also need to be carried separately. But at least now I can carry it all in one trip from the car.
William/Bill/Doug/Carl/Jeff/Chris/Donald - If you look closely, you can probably see some of the materials you've given me over the past year (dubbing blends/fur/yarn/flash/ribbing material/etc). Thanks for the materials. These are perfect for a travel tying kit.
William - I blatantly stole your idea for the DMC floss cards. These fit perfectly into the overhead projector slide holders. I was able to wind four feet of each material onto the cards, which is plenty for a number of flies. The cards can easily be refilled, once the materials are used up.
). I can't think of anything to add to it, so it will be very "similar" to yours.
