Part 3 — A Non-Rolling Thread Spool
Reading edition
A spool of thread may be kept from rolling by gluing squares of cardboard to the ends. The squares should be a little larger than the spool. This will save many a step and much bending over to pick up the spool. The spool, when it falls, will stop where it landed.—Contributed by Katharine D. Morse, Syracuse, N. Y.
