I just finished another trivet. I made it from plywood and got the pattern online. It took me about an hour and a half to make. I find the best way to make something like this when you have a pattern is to glue the pattern with a spray glue onto the piece of wood and then when you’re done cutting it out you can use a hair dryer to heat it up and then it just peels off without leaving any marks on the wood. I will post pictures soon along with the hope cross.
