A few people in our Twitter KAL are having some problems casting on their Traveling Woman Shawl, which is a triangular shawl. I took a few pictures today with some random yarn and needles in the hopes of demystifying the beginning cast on.
1. Cast on 3 stitches and knit 6 rows.
2. Pick up 3 stitches along the edge. I just grabbed my left needle and picked up 3 pieces of stitch from the sides. Note that my working yarn is still attached to the last stitch I knit in that 6th row.
3. Knit those stitches. Note that the leftover cast-on yarn (if you use a long-tail cast-on) is right under the last stitch you knit.
4. Now, pick up 3 stitches from your cast-on edge. Again, I just nabbed 3 bits of cast-on with my left needle. My working yarn and my leftover cast-on yarn are both between my needles. The work is also a bit tight and awkward since there's only one "raw" or unworked edge of the original rectangle.
5. Knit these stitches. You should now have 9 stitches on your needle.
6. This is the back of your work now. Your leftover cast-on yarn is in kind of a strange place. But once you tuck it in, you won't notice. You are now ready to begin the stockinette portion of your shawl.
