Some of you guys have so much more on the ball than me that I feel humbled in your presence. That frog of Toms is a case in point. I also like my frogs with markings on them, but I simply paint them on using a dowel, or brush or whatever. It never, ever would have crossed my mind to make them out of hot plastic and installing them in the mold before pouring the frog itself. If our frogs were placed side by side, Tom's frog would look like a frog. Mine would look like a frog that was used as a drop cloth. Big difference. I envy you guys that can think outside the box. I have trouble doing that.
