I knit a tuck stitch prayer shawl with a built in tuck pattern, 144 stitches x 900 rows. (Yup, not a typo.) Then I did a kind of twirly edging and ended up with about 2 yards of yarn left!!!
It's about 7 feet long by 24" wide. Enough, I think, to wrap around shoulders. If you want a little more specific directions, here goes. And, just about any yarn goes.
This one done on a Standard gauge machine but the idea could be adapted for any gauge machine.
Tension 7 (or whatever works with your yarn) Start with waste yarn and knit a few rows to get going over 144 needles.
Ewrap cast on over these 144 needles with main yarn. RC 000. Knit 10 plain rows. Set up machine for tuck using any tuck pattern built in or a punch card or hand manipulate if you are patient and persistent. Nah, that's just crazy. Knit to RC 890, turn off tuck, knit 10 rows plain and bind off using your favorite bind off.
EDGING: Try it on a swatch of the same type of yarn to see if you need to skip some shawl stitches as you go around, especially on the long sides. Skipping some prevents a ruffle. Unless you want a ruffle, that is.
Begin at the far right of your needle bed. With the wrong side facing you=== for tuck this would be the knit side==== starting in the middle of one side of the shawl, pick up and hang 3 edge stitches of the shawl with your 3 prong tool. Don't just pick up a loop, but a little more to make it substantial. Knit 6 rows. No need for weights because the shawl weighs it down. Pick up and hang 3 stitches to the left of those in work, K6 rows. *Pick up and hang 3 more stitches to the left of those in work, hang the far right 3 stitches onto the 3 stitches to the left of them. (There will be 2 stitches on each of those 3 right needles.) 6 stitches in work now. Push emptied needles out of work each time. Knit 6 rows.* Repeat from * to *. When you get to a corner, knit 8 rows rather than the 6 to get around the corner without a pucker. At the end, bind off and join to the beginning stitches, leaving a 12" yarn tail. Tidy up by sewing by hand with the tail of the main yarn.
Note that you'll be traveling down the bed, so you will most likely have to take off stitches and move them back to the right a few times. ok, quite a few times. I just use a double eyed needle to put the stitches on and move them.
This edging has lots of uses, baby blankets for one, and looks ok from both sides. It tames the edges so they don't curl. Don't know where I got it or what it's called.
I steamed the shawl quite aggressively and it turned out pretty nice. I'll be donating it to a local nursing home. Red is cheerful, don't you think?
Thank you yarn angel Bonnie---your yarn will be put to good use!
