Made in a simple rectangle then sewn up, all you need to know is the Knit and Purl stitches.
Available in three colour-ways.
They come in kit form which include all materials, knitting needles, sewing up needles and full step-by-step instructions.
You can find them HERE :)
If you don't know how to knit you can find a free download with step-by-step colour instructions HERE which you can download and keep to your own library so you can refer to it at any time :)
Would love to see photos if you make any :)
