The neckline looks to me like the center stitches may have been bound off or put on a holder and then the sides of the neckline worked separately with different balls of yarn, as you mentioned. I knit a sweater like this last fall. But I’m not sure why one side would have been unraveled, unless she discovered a mistake?
Good luck!!
]]>The blanket is very definitely hairpin lace, which I think goes by other names too. I knew how to do this in my youth, but have forgotten. It involved a giant “hair-pin” — a big u-shaped metal wire. You wrapped yarn around it and with each wrap, crocheted the loops together in the middle (between the legs of the pin). Somehow (another part I can’t remember) you fasten the loops of each new row together with previous rows. There must be on-line tutorials for this. If I did it as a kid, you can figure it out and finish the afghan. Ask your aunt to look through her remaining stash for the hairpin thingie. Likely it’s still there and she didn’t know what it was for. Oh, and you just use a crochet hook for the middle crocheting.
Looking forward to seeing how you finish these!
