I can relate - literally.
A crochet hook in my collection went missing once. I was in tears, trying to find it. It had belonged to my great-grandmother, who was a true master of the art of crochet. I did eventually find it, to my relief.
I keep hers in a special place now, and still use them. They're all finer gauge hooks, as she did a lot of thread crochet - tablecloths, bedspreads, that sort of thing. I also have the baby blanket she knit for me more than 30 years ago. You can tell it was commenced before I was born; the colors are pale pink, white and blue, and it was crocheted in a sc chevron pattern, with a pink fan edging on the long sides.
