I've finally finished off the next three tile sets for Dungeons in Blue, Set J, Set K, and Set L. Each of these sets contains nine 100x100-foot full-sized tiles, ready to drop into whatever virtual tabletop you prefer. These sets are also available in a bundle, Triple Pack Four, at a discounted price.
As usual these maps include GM and player versions, plus a full map key, preview image and brief read me. All image files are 100px per five-foot square PNGs. Here are the one-third scale preview images for these new sets:
