Last day of the month and the September UFO is now a FO. I ended up with changing pattern and restart.
I found the original pattern again on Knitty but couldn't figure out the needle size. Browsing on Knitty I also found Fallberry so I decided to change pattern.
And just in time for Fall I have a new pair of fingerless mittens.
The needle size is 3mm and I used Blue Sky Alpacas (sport Weight?).
