Hello!
In my opinion, fly boxes are outrageously priced. I'm young, poor, and still paying off my students loans. So, every little bit helps to feed this addiction!
I decided to do a *simple* step by step of how I make my own. It's really easy.
The best part is that each box works out to be about $1 in materials, and when the foam starts to look rough, you can just glue down another layer.
I like this method because it allows me to separate patterns into very specific categories. This way, I don't have to bring a big box with a variety of flies that I know won't work on whatever lake or river I'm fishing. Also, if I ever loose my flies, I don't loose ALL of them! I also always keep an empty one that I just fill up with a few select flies that I know will work well on whatever lake im on.
It works best with barbless flies, which you should be using anyways if you're in BC. Barbs seem to mash up the foam quicker.
