I needed a new busk for my corset in a hurry. My husband took the pattern to these people
and they cut out 2 from 1/4" polyvinyl. It works great.
They also have 1/8" polyvinyl if you don't need quite that much support.
Mine is triangular with a rounded tip. 4-1/2" wide x 13-1/2" long.
No more dried brittle wood for me!

A free paint stir stick from Home Depot did the trick for me. LOL
