If you only work on one at a time, plain knitting scarves finish quickly.
This is for Made By Hand. Size 10 needles, KFI Gaelic Aran superwash. No pattern – I just cast on an even number of stitches, then worked K2, P2 ribbing until I could wrap it around my neck twice.

Love love love! Someone who needs it will be very happy to have such a lovely scarf.
