I have about 3" to the right. I have my magnetic pin holder, my wooden skewer to guide fabric & pull the bobbin thread up, my snips to cut thread. I do have a plastic storage tower that fits underneath my sewing table & the top 2 drawers of that hold a lot. Those are about 3" deep & that is where I keep my machine feet, piecing thread, screwdriver, bobbins, etc.
Nice hubby you have!
