The arched gussets in these mittens reminded me of a vaulted ceiling. They are formed by simple M1L/M1R increases, strategically placed. The patterns are made from a simple cable and some twisted stitches, all easy to remember and execute.

The pattern has written instructions with charts for patterns.

Sizes
The pattern is written in one size to fit most. As written it is a nice snug fit but can be made bigger using needles one or two sizes larger than those stated.

Yarn requirements
Approx 155m / 170yds of double knitting weight yarn. Note: if you choose to use bigger needles you will need more yarn.

Other supplies
3mm (UK11, US 2.5) dpns, set of four
Note: you can work the hand using a 3mm circular needle and the magic loop method if you prefer, but you will need dpns for the thumbs due to the small number of stitches.
Cable needle or spare dpn
Stitch markers x 2 in different colours
