Kitchener stitch is a great way to graft two pieces of knitting together in an invisible way. While normally worked as knit stitches, it can also be worked in purl stitches which is great for joining garter stitch or when you are joining on the wrong side or a purl piece.
Stitches set up for grafting.
The stitches are on two needles held parallel. Cut your yarn roughly three times the length of the graft you are making (and add about 10cm for sewing with) then thread on to a tapestry needle.
1. Set-up: Insert needle purlwise into the first stitch on the front needle and pull yarn through.
2. Set-up: Insert needle purlwise into the first stitch on the back needle and pull yarn through.
3. Insert needle knitwise into the first stitch on the front needle and slip off needle.
4. Insert needle
purlwise into the first stitch on the front needle and pull yarn through.
5. Insert needle knitwise into the first stitch on the back needle and slip off needle.
6. Insert needle
purlwise into the first stitch on the back needle and pull yarn through.
Repeat steps 3 to 6 until all stitches have been worked, cut the end and weave in.
Remember not to pull your stitches too tight. You want the grafted stitches to be at the same gauge as the rest of your cowl.
