I use chain stitch for most of my edgings. It is versatile, easily manipulated, and adds a crisp, clean finished look to a design.
Similarly to peeling strands off a length of yarn for duplicate stitching, I also usually peel yarn for chain stitching.
It is possible to use full thicknesses but I wouldn’t recommend it unless you’re working on a very big piece or a very plain shape with no sharp corners or small curves. Full thickness chain stitch can be used to great effect when you’re after that look. Usually I’m after the more subtle, blended-in look achieved by using a thinner chain stitch.
I usually use a half-thickness of yarn. So, if my knitted garment is 8ply/DK and I have the same thickness yarn for the embellishment, I will split the yarn in (approximately) half. Four strands become two. Three strands become two. Five strands become two or three.
I have used a half-thickness of yarn, that is two strands of Woolganics (out of four in the DK weight yarn) for this example on a swatch knitted with 10ply/worsted Woolganics (which has five strands, if you’re curious).
Bring the yarn out from the back, where you want the stitching to start.
Wrap the yarn around behind the needle…
When you have a half-stitch jutting out, it is easy to just make the chain stitch go over the top of it, and it all blends in moothly.
Or, to end where you began, put the needle through behind
the legs of the first stitch…
… and put the needle back in where it came out from.
Tighten the stitch gently and you have a completed loop, without a visible beginning or end.
I hope this has been a help to you, and I’m looking forward to sharing more tutorials with you.
