D&D crafting – Dungeon Stone Tiles

Square tile sizes: one 12×12”, one 9×9”, four 6×6”, fifteen 3×3”, two 2×6″, four 2×3″, and five 2×1″.
Corners: eight straight corners (triangles), eight rounded corners, and eight half size rounded corners.

I used inspiration from Black Magic Craft’s build:

But added a few of my own sizes and corners to my collection. My tiles are 2 cm thick, only because the foam boards I buy are 4 cm.
