best-groove round elastic for men’s socks, what is that and where did you find it?
I apologize, I have only read in this moment.
I have owned it for a long time but you can find it in any resale of sewing threads and buttons, just ask.
This thread is very elastic about 5 or 6 tenths of a millimeter.

Also, I want the P3 shown in the teq advert.
@lewm that of the link is not the P3 but the PL 70II.
The P3 is the one I have in the photo in the avatar. :)
