Drop the 3.5mm gold Risen Slotted Tungsten Bead onto the barbless jig hook - you do want a slightly oversized bead here - and seat it in the vise with the curved section of the slot sitting on top.
Start the brown 6/0 thread right behind the bead, snap off the waste, and make multiple wraps behind the bead as a thread dam so the bead cannot spin. Then run the thread a little past the bend and back up a couple of wraps to the start of the bend.
Snip a fairly large piece of frosted craw Aussie Opossum Fur off the swatch, pinch the tips and stroke the underfur out. Keep that underfur - it becomes the body.
Measure the guard hair to about a hook shank length and bind it in as a tail, taking a wrap or two back into the bend so it angles down.
Wrap forward over the butts in tight touching turns, stopping just shy of the bead, snip the waste, and bring the thread back down the shank to just past the hook point.
Pull one strand of Wapsi Nymph Sili Legs, cut it in half and in half again. Tie one piece in at the rear across its middle, angled slightly down, then pull the forward-facing half rearward and bind that too, tight down against the base of the fur tail so the legs splay out.
Uncord the thread with a bodkin, spinning it counterclockwise and running the needle down it until it is fully uncorded, then split it with the needle tip and hold the split open with a finger.
Feed opossum underfur into the split thread - keep it rather sparse but enough for a bushy body - then lay guard fibres in sticking out about a shank length and cut the fur off flush on the other side of the thread.
Spin the thread into a dubbing brush, holding the rubber legs back with scissors or the bodkin so the spin does not trap them.
Wrap the dubbing brush forward in touching turns up to the head. Cut to the right length, the guard hairs land at the front; stroke them rearward as they come round so they finish as a collar.
Two whip finishes for security. Skip the head cement - the smell can put some species off - then pick the body out with the bodkin to release trapped fibres.
Pull the rubber legs back clear of your scissors and trim the belly flat, then pull the legs out and trim them slightly shorter than the tail.
