Thank you all for visiting my site, I truly appreciate your inquiries! Please note, I sell a service, and that service is hand-woven seat replacement. I do not teach, I do not sell supplies, and I do not sell the replacement "rush" inserts or any other type pre-made replacement parts. What I do for those of you looking for replacement chair seat inserts is weave you a new seat on your old insert framework. See my pricing guide for details.
