size 11 knitting needles and worsted weight yarn
Cast on 84 stitches.
Knit 7 rows (garter stitch)
After this point, ALL rows begin and end with 6 knit stitches. Don't forget!
With the 8th row, begin this 4-row pattern:
Row 1: knit all stitches
Row 2: knit first 6 stitches, purl 72 stitches, knit final 6 stitches
Row 3: PATTERN ROW (K2 tog) x3; (YO, K1) x6; (K2 tog) x6; (YO, K1) x6; (K2 tog) x6;
(YO, K1) x6; (K2 tog) x6; (YO, K1) x6; (K2 tog) x3. Remember also to begin and end this row with 6 knit stitches.
Row 4: knit all stitches.
Do this pattern until the shawl measures about 55 inches. Then knit 7 rows (garter stitch).
Add fringe if you like.
A very wise elderly knitter gave me this advice: on any row, slip the first stitch instead of knitting or purling it. This will keep your edges more firm and tight. I have found this to be a good piece of advice.
The alternating yarn overs and knit-togethers of the pattern row are what produces the "wave" in the shawl pattern, and it is very fun. Enjoy!
