So after watching a few video series on youtube i decided to make my own dungeon tiles. the materials are cheap and once you get it down it takes very little time.
basically you need a hot glue gun some acrylic paint and cardboard. after the initial purchase it was about $50 for materials, glue gun sticks, paint and a few other things. now i just have to buy more paint so the price per tile will drop significantly. plus cardboard is basically free :)
im pretty pleased with the way they came out so i thought i would share. the links to the channels i got the techniques from are linked in the video.
