A bit of advice here on the coloring. When you get an idea or get a color you want to duplicate be as exact on your measurements as you were on your mold making, especially if you are seeking some kind of translucent color.
I like to choose the amount of plastisol, get it ready to pour then add the color by 1 drop intervals. Some type of metal (spoon, etc) is good to put the colorant on away from the plastisol, then stir it in. You can get way too much too quickly if you try to add the colorant directly to the plastisol from the bottle.
When adding glitter, use measuring spoons and add small amounts then stir. If you use salt to make the bait heavier and sink faster, it will take a lot more colorant and you have to keep stirring constantly to keep it mixed.
Keep a notebook and pencil close by and write down the exact amounts of everything that you have in the formula so that you can reference it later. Don't think for a moment that you will be able to remember them.
Keep samples of the different colors in snack bags with the formula labeled on them.
These tips will save you time and headaches in the long haul.
