I was reminded of this when I cast on for Kim Hargreaves Darcy sweater. (see previous posts on Darcy here and here.)The instructions say to work in moss stitch, but if the directions for moss stitch are included, I couldn't find them. Luckily I knew how to make moss stitch thanks to Mon Tricot. It is simple: establish a row of k1, p1, and proceed to purl the knits and knit the purls throughout.
But a few days earlier I had been looking at instructions for the Minimalist Cardigan from Interweave Knits (Fall 2007). The stitch pattern for this sweater is also called moss. This pattern did include the directions for moss stitch, but the moss stitch it described was a version of double moss, not the moss stitch I knew from Mon Tricot.
I remembered that the American and British versions of moss stitch are different. When Americans say moss stitch they usually mean double moss. Maybe it's not a big deal, but if you didn't know that, you might use the wrong stitch in making the Darcy Jacket, since the stitch pattern isn't specified. Anyway, I went looking in Mon Tricot, and in my other stitch dictionary, Harmony Guide to Knitting Stitches and found some variations.
Pictured above are the Mon Tricot versions of moss and double moss; single moss is on the right. Moss stitch is a skewed variation of rib in that it alternates knit and purl stitches and works knits and purls on both sides of the fabric. Single moss is, as mentioned above, simply k1, p1 throughout except you knit the purls and purl the knits. Working on a multiple of 2 it goes:
Moss Stitch (also called Rice Stitch) - row 1: k1, p1; row 2: as row 1
Double moss, in the Mon Tricot version is a doubling of moss stitch in every way. Instead of k1, p1, it goes k2, p2 and covers 4 rows instead of two. The instructions don't make this clear, but it boils down to this - knit the purls and purl the knits on the odd numbered rows; knit the knits and purl the purls on the even numbered rows. Working on a multiple of 4, double moss goes:
Double Moss Stitch - row 1: k2, p2; row 2: as row 1; row 3: p2, k2; row 4: as row 3.
Double moss is much chunkier than single moss. Single moss is fine textured and daintier looking, but the fabric it produces has a lot of firmness and body. I like single moss better, but of course each has its uses. All moss stitches look the same on both sides.
Harmony Guide offers a different version of double moss stitch (pictured above). This is the version used in Interweave's Minimalist Cardigan. The hunky Mon Tricot double moss is on the left. The Harmony version, right, uses k1, p1, rather than doubling it to k2, p2, but works over 4 rows instead of 2. It is daintier than the Mon Tricot double moss. It is worked on a multiple of 2 + 1:
Harmony Double Moss Stitch - row 1: k1, *p1, k1; row 2: p1, *k1, p1; row 3: as row 2; row 4: as row 1.
As with the first double moss, this one boils down to knit the purls and purl the knits on odd numbered rows; knit the knits and purl the purls on even numbered rows.
I have also noticed that the names moss and seed are sometimes used interchangeably. In the interest of clarity, I find that seed and moss stitch are not the same. Pictured below is a scan from Mon Tricot showing seed, double seed, and 2 variations of seeds:
Seed stitch uses purl bumps decoratively on the right side of the fabric, unlike moss which depends on the interaction of knits and purls to form the fabric. Seed stitch is thus one sided. The even numbered rows in the two basic seed stitches (seed and double seed) are all purl, like stockinette. Single seed is basically stockinette (k on one side, purl on the other side) with purls superimposed on the knit side in a staggered pattern.
In her comment on the above post, the nameless blogger of Wool Enough and Time has pointed out that what I am here calling moss stitch is usually called seed stitch in the United States. Sure enough, I was coincidentially looking at Cheryl Oberle's Folk Shawls and Barbara G. Walker's Learn to Knit Afghan Book and see that what they call seed stitch is what I describe above as moss stitch. This adds to the confusion especially since my Harmony Guide, which I cite for a variation of double moss, uses moss stitch as the name for the 2 row, k1, p1, not seed.
Can you tell that I like classification and organization? I suppose that aside from my quirk, the names don't really matter, as long as everyone knows what you're talking about. Cheryl and Barbara Walker give directions for the stitch that they call moss, so no harm done. But it does bother me that the Kim Hargreaves Heartfelt book does not tell you how she wants moss stitch done. She just tells you to do moss stitch. The saving grace is that the photo of the sweater shows the stitch clearly, so you can do it whether you call it moss or seed. Thanks Wool Enough.
