Protecting Plans in a Shop
The magazines I used in the shop, for making a few things from plans, became so soiled that they were unfit for the library. I now keep them clean by using a covering made of an old picture frame from which the back was removed and a plain glass inserted in its place. This is placed over the magazine or other plans on the bench and keeps them clean, dustless, open and flat.—Contributed by H. J. Blacklidge, San Rafael, Cal.
