There might be easier ways to undertake such a project, but I used what materials I had on hand in order to keep costs minimal - especially not knowing if my idea would work. The original mold and box I made lasted 5 castings before it became unusable. That was due to my lack of reinforcing the mother mold with fiberglass. I then created Version 2.0, which is the method I have been using since and am teaching you today. To date I have made 15 of these 350 lb.+ Buddha castings all of which are currently nestled in various gardens belonging to my friends, family and clients.

Step 1: Choose what you want to sculpt.
I purchased this head a long time ago at a flea market and wanted to create a bigger version. I chose to only create the front half of the head in order to avoid any undercuts and to keep it a one-piece mold. I placed tape on the head to indicate my cut-off line and took photos.
