Cork is a type of modified wallpaper/backdrop block that lives in the Decoration section of inventory along with the other wallpapers. This block is one square block in size and has no collision. Like all backdrops, cork layers behind items and blocks that have collision.
How to Obtain
This block generates naturally, but only as backdrop in specialized gift box bunkers in holiday arctic biomes. You can also craft it or trade for it in a market world.
How to Use
Use cork when you want a warm, corky feel. Unlike most background blocks, which are highly patterned, cork has subtler markings and thus is good for when you want a relatively uncluttered backdrop for a build. Cork is not used in the crafting of any other blocks or items.
Cork is one of the numerous backdrops.
