I am about to finally gain a sewing room! I've decided on the only bedroom with no carpeting, and its also the largest one. But I'm afraid to damage the 75-year-old oak flooring with my rolling chair, and maybe rolling over a dropped pin. The steel shelving legs will also do damage. And I'm also limited to what I can mount to the walls which are lath and plaster, so I'll be using those stick-on hooks wherever possible. Any damage will be MY job to fix (DH has always claimed he's not handy with that sort of work, although he's the first to jump in and tell me how to do it!). Man, I wish I'd thought of that declamation first!! So anyway, has anyone ideas of how to protect the floors short of carpeting? Those plastic protector mats are meant for carpet, they have grabby nubs on the back
