Please note this is an Extension Only - The Bernina Studio Frames offer an economical solution with a significantly smaller footprint compared to the Classic Frames. Elevating to a stand-up frame presents the advantage of being able to fully load your quilt project while maneuvering the sewing head with ease. Furthermore, stand-up frame models provide the added benefit of conducting pantograph quilting from the rear of the machine, particularly if you own the Q20 or Q16PLUS.
