Kitchener Stitch (or Grafting)
This technique joins live stitches together in an elastic, invisible seam. The method can also be used over bound-off stitches to make a strong, stable seam.
With an equal number of stitches on two needles, and right sides facing up, hold the needles parallel to each other with points facing right. Thread a blunt tapestry needle with two to three times the length of the area to be joined. For live stitches, work as follows:
Step 1: Insert threaded needle into the first stitch on the front needle purlwise (as if to purl); leave stitch on needle.
Step 2: Insert needle into the first stitch on the back needle knitwise (as if to knit); leave stitch on needle.
Step 3: Insert needle into the same first stitch on the front needle knitwise slip stitch off needle.
Step 4: Insert needle into the second stitch on the front needle purlwise (as if to purl); leave stitch on needle.
Step 5: Insert needle into the first stitch on the back needle purlwise (as if to purl); slip stitch off the needle
Step 6: Insert needle into the second stitch on the back needle knitwise (as if to knit); leave stitch on needle.
