David - nice table and chairs.
I've made a total of 12 chairs so far but they were in sets of no more than 4. My son has 4, my daughter has 4 and I have 4. Sometimes I made 4 at a time but for my daughters I made 2 and 2. Hers and mine are based on a plan from Woodsmith that has a padded cloth seat and 5 curved wood back slats. All 90 degree angles. I still have the plywood patterns for this chair, I think, and tentatively plan to make at least 4 more. I will have to get a bandsaw first, however. Lost the last one in a move.
