Since I have not been tying for long I think I probably have much less in the way of tying materials then a lot of people here. I keep all of my fly tying stuff in the two containers below. They are starting to get kind of stuffed so I'll need to expand soon, but one thing I can say is that these two containers are very easy to pick up and take on a trip. I got both at Walmart and I have to say the modular boxes on the right are pretty cool as you can attach several together. With these it would be really easy to put together a "small kit" as Ray suggested that cover your basic frequent flyer patters.
