Incidently, I've found an alternative (though a more visible one) to the monofilament for mounting. Ok, so I'm a recycler.... but here at the office, they're always running new comm lines. Those folks will run lines, trim the excess, and leave 3-4 foot remnants for the clean-up crew! Those remnants strip down and make GREAT mount supplies! They're a bit more kind to the roots, so you don't need to use as much moss to protect them. Really helps when you're mounting vandaceous plants that really don't want much on their roots! Plus.... you don't have to be a master fly-tier to get a good knot! A couple of solid twists and you're in business!
