Step 2: Prepare the Parts for Casting
If you have only a small hole made by the wire or needle and thread, don't worry about sealing it--the alginate probably won't leak.
Since the alginate will set quickly, ensure the parts are flat, attached and ready to go before mixing alginate.
If your pig's feet have been cut in half (like mine), cast two. You can join them together to make a complete foot later.
