We just recently released a set of 9 texture-based PBR cycles materials. Mostly woven bamboo, wicker and rattan. The interesting part about these is they were created as tileable 3d models and baked directly in Blender. In my experience, the results are actually often better and faster than achieved with other tools, since the true 3d representation enables handling of the materials as real physical objects. As with all the materials, you can get them through the BlenderKit add-on for free.
