Ok, so Mobius has caused a few people headaches. I just want to say thank you to the few people who contacted me about this. I hope this helps!
The crochet language I use in this is in UK. I got nervous and forgot to translate to US while filming. The "treble 10 together" I mention is a "double 10 together" in the US version of the pattern. For further translation help, I have this, which may be useful.
Also, my voice isn't normally as grumbly as this. I'm just after a cold, so I'm still a bit froggy.
