Oh, I have my Grams' here in the sewing box. I only darn my woolen socks when the heels wear down. I gave up on the cotton socks a long time ago. My "egg's" aren't as fancy as yours. No handle or prettiness to them, but very functional just the same. Grams dried gourd's of some kind. You can still hear the seeds inside rattle. Darn things must be over 60 - 100 years old. The smaller ones are for children's socks.
