Does anyone know what the minimum weight would be for a good card stock when printing front and back? FH and I printed a test for our programs last night on some shimmer card stock that I had left over from our RD invites and we could see through the paper to the back. The package said the weight was 65lb, which I know is a bit low. We may end up having to order online now so I want to make sure I get the right weight for these so that there is no see-through. Anyone have any idea? I found some online that looks nice that is 95lb...would that be good enough?
