The Cabled Mitts are worked from the bottom to top.
They are quite stretchy so they should fit most.
The pattern gives the written instruction as well as chart.
Worked in 2 skeins of Garnstudio Drops Andes. I did not use 2 full skeins, only about 10 metres from the second skein.
110m/120yards of chunky/super bulky weight yarn should work.
