Its been a minute since I messed with it, but locate a mold if you can. Some of the kits where you make your own mold can be finicky, unless youre looking for peckered lizards....
you can get pretty creative by adding scents like garlic, etc.
There are also bait dips and markers to tease up the colors if needed as well. Use the base color for the body and then dip it, as opposed atttempting to mold two different colors together.
Don't overheat in microwave, stuff reeks beyond belief.
It's fun if you like tinkering, but I never ran the ROI calc on it, as picking up a pack or two of Zoom works well for my current needs
