I know I'm not the first one to do this, but I think it is a very cool idea that I would like to share. I've seen people out there make a homemade magnetic fly box, and that's exactly what I decided to do this last weekend. I bought the box at the local fly shop, and bought magnet tape at Office Depot. Spent a little time piecing the magnet into the bottom of the box, and adding the numbers to distinguish sizes of flies. I've really only put about an hour of tying into this box, mainly little blood midges and yong specials. I think this little box will come in handy in a few weeks when I head to the Juan with a group of buddies. We have a group of 12, and only me and one other tie our own flies, so I know I'm going to need to crank out some flies to keep everyone fishing. I'll just let this box get passed around, with people free to choose the size of flies they want to fish. Even the first time fly fishermen will be able to get a sense of the size of flies they are fishing.
