Here are some garden ideas.
Take a look and see if there is something that that gives you the look you want. If you meant you want to cast your own Buddha, that's different. The only one I found was just a head and the work to make it was quite extensive. Here's instructions for doing that.
I hope one of these helps you. Wishing you the best.
Borrow someone else's Buddha, make a mold and pour in concrete.
What do you want to make it out of. plant wire? cement? wood? Just remember Buddha is most often pictured with African curly hair, long long earlobes. A big belly. A garden Buddha is an interesting sounding project. Please keep me posted, "firstname.lastname@example.org" is my email address. I'm also on facebook and LinkedIn.
I'm trying to make large Buddha face or full statue for garden .
