I have no chance to do tutorial as i have only one broken chair, but you can see the main idea. if you like it and want tutorial, just let me know it, when somebody ask, i will work on a detail information.
the other picture you may guess it's the rest part of the chair.
together with my mum, we made also a garden plant table, with fruit wooden boxes & nylon bags.
the PVC pipes are for winter termal cover use.
just tell me which part you like to see picture, and i will take it for you.
