You can save money if say all you use are 5" senkos in green pumkin. Save your used plastics, get some fresh plastisol, a yard sale microwave, Pyrex cup, and a hand pour mold. Problem is once you start you will buy more molds, etc. to try which starts to get expensive. I can say that about 3 in 10 molds I have saved me money and have paid for themselves several times over. The other 7 I doubt if I re-coup the cost of the mold in the next 10 years. Since I like making my own stuff the way I want it the cost does not matter and is just part of my fishing budget.
