besides the things others have mentioned--I usually "float" quilts when I work on LA and use magnetic bars; an antique muffin tin for notions, my cutting table is an adjustable drafting table and my stool at the LA is a drafting stool. I use net scrubbies to remove marking chalk; a laser level for squaring; the toe of an old stocking instead of a net on thread cones; drafting T-square for squaring up; freezer paper; flannel backed table cloth (as a design wall); my phone camera! And in the long arm work space, I use a folding drying rack to hold tops waiting to quilt & also use a pad and quilt on the dining room table to press wideback or tops; a handheld steamer.
