This is my first adventure in 4-ply!
I bought the wool at the hobbycraft show at the NEC, from www.lakesidecrafts.co.uk.
It's a gorgeous self striping sock wool called Regia, 75% wool and 25% polyamide.
I've used less than 50g altogether.
To knit the mittens couldn't be easier.
Cast on 55 stitches on 3mm needles, and knit until it measures 16cm, then cast off.
(For bigger hands knit a few more cm.)
Sew cast on and cast off edges together for 5cm, leave a 5cm gap for your thumb, then sew the rest together.
Make another one for your other hand!
You can even wear them upside down!
