I just downsized to a small place. Needed place to put machine to sew. Found a desk to put in bedroom. Now the surprise!!! There is a pullout shelf for computer keyboard. Great to rest fabric on pwhile sewing. Easy tp lay fabric when ripping a seam. Just now finding new uses for this extension. Of course, it puts me a bit farther away from machine, but I compensated by setting machine closer to edge of desk. Hopes this helps someone.
