SEED STITCH (OVER AN ODD NUMBER OF STITCHES)
Seed stitch over an odd number of stitches is worked the same as seed stitch worked over an even number of stitches. When you’ve cast on an odd number of stitches and you are alternating knit and purl stitches, all rows will begin with a knit stitch. The important thing is that when you see a purl stitch, you knit it and vice versa. If all the rows were worked as stitches appear (meaning that when you see a knit stitch, you knit it, and when you see a purl stitch, you purl it) you would be knitting rib stitch.
Step by step
Start the repeat by knitting a stitch.
Bring the yarn to the front of your work and purl the next stitch.Repeat this sequence until you finish the row.
When you finish, turn your work and work the stitches in the opposite stitch as they appear. This means if you see a knit stitch, purl it, and if you see a purl stitch, knit it.
Repeat until you have finished the row and have knitted the desired number of rows.
