I’ve been secretly vetting this thread for a couple years now and after using it extensively, I finally feel comfortable adding it to our shop selection and actually recommending it to my customers. I don’t take this lightly and wouldn’t point you to a tool or material that I hadn’t used so sometimes it takes a while.
Semperfli Nano Silk 6/0 is a 100 denier GSP thread that is incredibly strong and builds up virtually no bulk on the hook. Perfect for spinnimg hair! Nano Silk lies very flat but doesn’t spread uncontrollably like most other GSP threads and the spools don’t get all ratted up over time, either.
