Kitchener Stitch
Kitchener Stitch is a beautiful way to joins live stitches together to create a flat, invisible seam.
To begin, cut a sewing tail 3 times the length you wish to sew and thread it onto a tapestry needle. Whenever possible, use the working yarn attached to one of the pieces. Hold the needles with the live stitches parallel in your left hand with wrong sides facing (or right sides facing — the pattern will always specify!)
Step 1: Insert the tapestry needle through the first stitch on the back needle knitwise. Leave the stitch on the back needle.
Step 2: Insert the tapestry needle through the first stitch on the front needle purlwise and pull the yarn through, leaving the stitch on the front needle.
Step 3: Insert the tapestry needle through the first stitch on the back needle purlwise and pull the yarn through, dropping the stitch from the back needle.
Step 4: Insert the tapestry needle through the first stitch on the back needle knitwise and pull the yarn through, leaving the stitch on the back needle.
Step 5: Insert the tapestry needle through the first stitch on the front needle knitwise and pull the yarn through, dropping the stitch on the front needle.
Step 6: Insert the tapestry needle through the first stitch on the front needle purlwise and pull the yarn through, leaving the stitch on the front needle.
Repeat Step 3 to Step 6 until all the stitches have been worked. Adjust the tension of the sewing tail as you go along, being sure not to pull too tightly.
Take your time with this one. Kitchener does take a bit of effort to learn, but once you catch your rhythm it flows and comes together so beautifully.
