When a pattern mentions "seed stitch," what does it mean?
Seed stitch is when you work a k1, p1 across the row, and on the next you purl the knits as they face you and knit the purls as they face you.
So if end the row with a purl, start with a purl. If you end the row with a knit, start with a knit.
On the first row you need to (k1, p1) repeat across. On the next row and every row thereafter you purl the knit stitches and knit the purl stitches as they present themselves on the needle to be worked. If you don't know how to do that, look at the sticky thread on the first page of the "How-to Questions" folder about "knit the knits and purl the purls". But you want to do the opposite of the way the stitches present themselves instead of the same, or you will get ribbing. Seed stitch is alternate knit and purl with those offset each row. It produces a very bumpy look, lies flat (it doesn't curl) and looks the same on both sides.
