Having just recently started I would add one more thing here. Pick a bait you use a bunch of and start with 2-3 molds that are exactly the same. When I started pouring I had one 4-cavity mold for stick baits. It took damn near 1 hour to make 20-30 baits. You may have to spend a bit more up front, but you will be glad you did. Having only one mold can be a slow process... heat, pour, demold, heat, pour, demold, etc. You'll spend more time at the microwave than you like.
