Double Knitting Selvedge

 The edges on double knitting can be done many ways.  The one I like is listed below.

1. When you reach the last two stitches in a row.
2. Normally the next stitch will be a purl stitch.
3. Take the two strans of yarn to the back of the needles.
4. Slip the second to that last stitch as a purl stitch. (this stitch would usually be done as a knit stitch.)
5. Take only the one strand of yarn to the front of the work. 
6. Slip this stitch off the needle as a purl stitch. (This would normally be a purl stitch.)
7. Turn your work.
8. Knit the first stitch of this row through the front of the stitch.
9. Pull the yarn between the first and second stitch to the front.
10. Purl the next stitch. (Second stitch in the row.)
11. Continue the row per the chart until the last two stitches.
12. Repeat steps 2 through 11.
