I took out the texture from the BookNook base game bookcase and used it to make this wooden recolor of the Storybook Column Arch that comes with OFB. Check it out:
I am thinking of making another recolor, this time using the same texture but with stone at the bottom. That way, it would look like I have wood-and-stone arches in my game!
It's going to be used in my current Medieval-themed neighborhood Driftwood! I think I would use it for my cloisters (monasteries and nunneries and abbeys).
