The pattern is created for a thicker yarn. I recommend to use at least sport-weight. The sample pairs for this pattern were all knitted on Addi Turbo circulars (US size zero) with sport weight Regia Tweed, and fit small to medium. The dimensions are 9 cm wide and 24 cm tall. The gauge is approximately 30 stitches X 35 rows in 10 cm.
The PDF also includes instructions for a fingerless mitts.
