These mittens are worked in slip stitch crochet to create a dense and warm fabric.
Working in a spiral, the hand and cuff are made first followed by the fingers and mitten tip. The yarn is re-joined to make the thumb and thumb tip. The cuff is made last and is worked flat and then sewn on with a simple whip stitch.

I originally developed this pattern for my crochet group, “The Riverhouse Hookers” to learn about slip stitch or Bosnian crochet - working in the round and flat. I have incorporated some of the class notes into the 9 page pattern so it includes additional information, photos and tips, as well as the pattern instructions for making the mittens.

Available in three sizes, with finished hand circumferences:

Size 1 : 15.5cm, Size 2 : 18cm, Size 3 : 21cm

These mittens are best worn with positive ease so choose the nearest size that is wider than your hand.

Materials:
Thick Aran (sample shown uses Artesano Aran in Nightfall).
2 x 100g (288 yards / 264 meters) is enough for all sizes.
5mm & 6mm hook (see note about hooks below).
Tapestry/Wool Needle.
Thin thread for marking the gusset increases (optional).
4 locking stitch markers.

Hooks:
For slip stitch crochet it’s best to use a pjoning or sked krok hook (these are generally one size).
You can use a normal crochet hook. Either choose one with a sharp tip or you can carefully modify the head of a cheap bamboo hook with a Stanley knife/craft knife and smooth with a nail file/emery paper to make the tip smaller.
Hooks with blunt heads or very rounded heads are not suitable as you will struggle to get the hook through the stitches.
