Long before industrial mass production ladies (and probably some men) darned their socks and gloves to repair any holes. Let's face it: someone probably hand knit those socks and gloves, and maybe a sweater or two, too, so after all that effort it was worthwhile to mend them!! After the industrial revolution folks were still darning, especially during the war years when commodities were scarce. Use and re-use those clothing items were the by-words. Darners come in many shapes and sizes to accommodate whatever needed to be darned. The most ubiquitous of those is the so-called "darning egg". Here are a few examples, the most noteworthy is the one on the bottom that is metal with a little girl etched in it.
A very typical shape was the egg-on-a-stick type. They come in different sizes, some painted, some not. These are probably from 1900-1930.
Glove darners, anyone? The painted ones date from 1900-1920. Note the different sized ends of the black darner at the top. The darling little one at the bottom is unusual: I've never seen one like it. I guess you just dropped it into your glove finger and somehow fished it out when done.
This is probably more than you ever wanted to know about the lost art of darning. Nowadays I can darn on my sewing machine, or touch up sweater holes by hand with a needle and thread. We no longer need these items of repair but they make very interesting collectibles as a reminder of what women and children used to do years ago to keep their, and their families, looking neat and tidy.
