We're going to DisneyWorld in a week and I decided to make my two boys handmade autograph books to take on the trip. I made the front cover out of cardstock with die cut shapes and letters glued down with a ZIG glue pen. Knowing how rough my boys are on things, I decided to try out my new Mod Podge (matte version) to seal it all up. I used a 1 inch wide foam brush and put a moderate amount on and smoothed it out with the brush as best I could. It's fully dry now, but you can still see the brush strokes. AND, the formerly flat cardstock is now buckly and wavy. Any ideas what to do about this?
My plan is/was to mod podge this mod podged cover to a piece of thin cardboard (cereal box) and mod podge another piece of cardstock on the back of the cover. The idea was that in addition to sealing the detail on the front, the mod podge would be the glue that holds the cardstock to the cardboard and hopefully add a little stiffening in the process. But now I'm not sure that mod podge is the right product to use. HELP!
