After several months of deciding what I was going to use for making my roadways I went with 400 grit wet/dry sandpaper. Love the look and by taking a foam brush and brushing it longways it adds that faded blacktop look. Here is my question,what do you use to hold it down. I started with white glue(elmers) but I have not had alot of luck keeping the edges from curling up. What should I do? Thanks
