From publisher blurb:
Lair of the Stitch Witch Quest Maps is a collection of 12x18 map tiles suitable for poster printing.
The pdf in this collection contains four 12 inch by 12 inch map tiles. This product also contains 300 dpi jpg versions of the files for use with VTT programs.
This is designed for use with our 5e Compatible adventure, [Lair of the Stitch Witch], but is suitable for adaptation into ANY game.
Some of this art is graphic or disturbing, so user discretion is advised.
