I swear to all that is Good and Holy...
all I did was sit in a chair and knit.
I did let go of the needles to measure, but there is no logical reason for this to have happened:
Seriously. I never left the chair.
I think I can bend aluminum with my mind.
(They still work just fine, thankyouverymuch. Though I probably won't use that particular needle to cast on anymore, just in case.)
