Knitting gloves with fingers can be a bit of a challenge. To make it easy for you, these gloves are done in stocking stitch with a bit of garter stitch only – but nonetheless with a lot of effect due to the contrasting yarns and all the pointy bits!
The given tension will result in a circumference of 19cm. For a well fitting glove it is best to make it a little smaller than your hand circumference (maybe about 1 cm less), so that it stretches somewhat around your hand, without overstretching. You can adjust the size slightly by changing the tension, e.g. a tension of 32 sts per 10 cm will provide a circumference of about 18 cm, and 28 sts per 10 cm one of about 20 cm.
