The Thatched Wall is a straw-like looking building block created in your Crafting Menu (default key "Q") or at Crafting Tables (that still exist in worlds created before R22 on September 16th 2015), but only after the crafting-recipe has been unlocked upon taking Vines. To craft 8 Thatched Walls at once, you'll need (as of R27 in January 2016): * 2 (blocks of) Shredded Leaves, made from any kind of tree-leaves in a Processor and * 1x Vines taken from Cragwood-trees in Forest-biomes or Woodlands-biome, or from Wildwood-trees in Jungle-biomes (no Power Cells are needed)
