making soft plastic fishing lures need not be a very complicated affair and the best ones tend to be the simplest. I recently made a eel jig head out of biro lid and thought it could do with some homemade paddle tail rear ends to go with it and there is nothing like spending a hour or so making a master and mold that can be used to produce enough lures to fill a tackle box for a few seasons.

For the soft plastic I re-melted a mix of soft plastic worms and other things which worked but came out a little more stiff than i would like . Virgin plastisol can bought from a range of companies. I normal used Lurefactors who are in the uk https://lurefactors.co.uk/
