With the exception of tying the skirt, this is an assembly project rather than a scratch built bait. A wide selection of pre-made skirts are available from LPO if you don't care to thread wrap, wire tie or use a rubber collar.
The well-designed and painted head, Bio-Silk silicone skirt material, the SwimTail trailer and the hex willow blades all come from LurePartsOnline.com. The German round nose pliers, split ring pliers, beads, clevis and swivel are from barlowstackle.com. Both of these component suppliers have deep inventories which have been satisfying my bait making needs for years.
