Seed stitch, moss stitch

I thought seed stitch and moss stitch were the same thing, at least that's the impression I get from Debbie Bliss. Those weird British people with their tea and crumpets and accents and such.
But Barb's here to right my wrongs. (And she'll be doing that alot, I'm sure)

Here's Barb's take on Seed stitch

...It is sometimes called Rice Stitch or Moss Stitch, although it is different from true Moss Stitch. Seed Stitch is really a k1, p1, ribbing broken on every row, so that every knit stitch is placed above a purl stitch and every purl stitch is placed above a knit stitch.

and her take on Moss stitch

...It should not be confused with Seed Stitch, as the latter changes from knit to purl stitches on every row whereas Moss Stitch changes every other row.

and there you have it, they really are different. Barb's so smart.
