Don't really build dining tables and chairs cause they're large for my space/tools and they're a pain in the ass. When I did/do, I had three designs for them. Dining tables are $8K and $11K. Chairs are $950 and $1100 each. But, I use high end wood, hand applied finishes, much better joinery, and is unique and completely different than mass produced. These pieces will be around a lot longer than we will!
Remember, the $100 at Wally World will turn into a lot more when Skeeter hops up on it and it collapses
