I tried FMQ with no thread last night on the treadle. It was awkward and felt as if I needed more working room.
I took the top off of a school table and put it on the treadle stand. Then I brought a stand up from the shop (I actually brought two up, the first one didn't fit right) and set it up between the treadle and the window. The top lifts up so that I can access the sliding glass door. I covered it with an oil cloth table cloth I was ditching and VOILA.
