I left the socks on my mom's bed in the cabin we occupied last weekend, for her birthday weekend (one of the decades...!). She didn't say anything when she arrived, so I brought them up. She said she thought the tops were unfinished. I had bound off using much larger needles because I was worried that the tops would be tight, so they ended up looking picot-ish.
After I assured her that they were done, she tried them on. She was really pleased. She proceeded to wear them the rest of the weekend, at least in the morning and night, until it got too hot in the daytime to wear wool socks. And she ranted to anyone who would listen about how incredibly well they fit her feet, better than any other socks she'd ever worn!
