Sculpting arm sleeves

I need guidance on making some silicone forearms. I'll be making a mold of my arms and casting them. I'm planning to sculpt the forearm pieces in clay. I'm not sure of the next steps - any suggestions? I need the final pieces to be open on both ends so they can slide over my arms with my hands showing.

Thanks!

You would need to make a hard mold over the whole thing. The clay would then be removed. The cast of your forearm becomes the "core" of the mold. Then you fill the gap with whatever silicon you plan to use. These are just the very basic steps, you may want to check YouTube for detailed video tutorials.
