The wheels did the trick. I evened out the two tables and quickly sandwiched a top and back (both pieced) and sat down for the big try out. I also switched out my chair to one that raises and lowers more accurately.
Two hours into the quilting and I had to break for a doggie walk. Back soon afterward and I put in another hour of quilting. I am 3/4 done with this 48x62" top.
The table makes it very easy to guide and slide the quilt and I don't need any other mechanisms to accomplish the work. Simple is best. Of course the tops I am quilting are not fancy, but functional and I am happy to be reducing the UFO bin as I play. I am excited to finish the rest this way, with allover quilting, so fast and still decorative.
These are the two unrelated (except by yellow) that I quilted together.
