I finally gave up. Ibought one of those Lifewtime tables that is about 26" x 17" and has 3 different heights. I use it a lot as I do get together with others at our homes.
Luckily when I go to sew-in we tend to have only 2 people per table so each can have an end.
I do like the idea of adjustable legs from IKEA though and believe the guild or LQS should provide them as a service to those attending.
