Living in a haunted house, huh? I guess that’s what comes of not having straight needles. lol That is weird though. I hope it doesn’t mean there’s a problem and you’ll have to replace it.
I have some never use 'em straight needles and Tunisian hooks in a glass jar. My dpn, used mostly for fixing mistakes, are in a candy box. My fixed circs for socks and a couple 16"ers I decided to try supposedly reside in a plastic shoebox type container but in reality most are not at home, some are in use and others are hiding. Interchangeable tips are in the plastic cases they came with and the cables for them in a zippered pouch. I use the interchangeables all the time. Luckily the three sets all use the same cables.
When I get caught up in projects I have a tendency to accumulate a lot of knitting paraphernalia that I have to sort out and put away.
