I did a google search recently for "tenkara line spool" and found one pic of a guy that made his own "EZ Keepers" using two big buttons and some elastic cord. Gave it a try and in my mind it works great. The best part: I took/stole/borrowed/pillaged the materials from the wife's sewing room when she wasn't looking. So it was free. That and I ended up making a couple of wooden line spools like some of the other pics I saw. The work great for storing the line between fishing sessions.

Flyfishing is a drug. It's addictive, it can be expensive, not many others will understand it, it is possible to get others hooked, and everyone has a favorite place to get their fix, but there's no hangover in the morning (from the fishing at least).
