I am making a 24" tall x 42" wide 1 1/4" thick PVC sign for a customer.
1st time using PVC, sign is single sided, bottom portion v carved and the top is routed pocket .25 deep with raised lettering. My question is, should I also rout the back side to help with warping? Also what would be a good way to mount it? it will be mounted onto a block wall. Thanks in advance for any help
