Over on nycake.com, you can get a "Brick Texture Rolling Pin 13" x 1" long" here.
Also, on fantasticmaps.com, check out "How to Design a Town Map" here.
Finally, on theDMsCraft YouTube channel, an oldie but a goodie. Watch the "RICKETY LIFT Dungeon Terrain for D&D & Pathfinder (DM's Craft #124)" from early this year. Enjoy!
