Since Tracy asked I'll try to explain the ssk. Iris Schreier herself said, she's using a different method now, then in the book. You see here both sides of the beginning of the triangle scarf. One side (top) has a neat little ridge, which is not prominent but clean and nice. The other side (down) has no ridge at all.
This is how I do it now:
When you come to the point where you knit together both triangles (or whatever- diamonds etc.) you use the last stitch of the first triangle and the first stitch of the new triangle.
slip1 knitwise, slip1 purlwise, put both back on left hand needle, knit those two together knitwise, turn, slip1 knitwise, knit to end.
That's it. That's what I did this morning and that's what it looks like.
I've tried everything else and this was the neatest fabric.
I hope it helps. ;o)
