⇒ where’s the yoke for opening tins?

The Garter Yoke is a no-nonsense warming layer around the neck without extra bulk; perfect for under snug fitting coats & jackets. It is more form-fitting than the typical loose cowl, and comes down around the shoulders for extra warmth.
The garter stitch fabric is super stretchy, so the sizing is very flexible, with plenty of room for growth. Smaller sizes can be worn to cover just the neck & collarbone area - the toddler sized yoke will fit over a large adult head, & cover just the neck area for example.

The pattern is written in five sizes - Baby, Toddler, Child, Small Adult, Large Adult - and in a choice of four different yarn weights - 4ply, sport, DK or aran weight.
It is begun with a provisional cast on, knitted flat & shaped with short rows, and finished with a three-needle bind off. Instructions are also suggested for knitting without the provisional cast on, with a sewn seam.
