Cast on 8 or 9 sts and knit a row, then in the next row k1, yo across to the last st, k1. If you want a garter border, then k2, yo k1, to the last 2 sts and yo k2. Work a couple more rows, then on the 4th row, repeat the k yo sequence. Then work 7 more rows and on the 8th row do the incs. Work 15 rows and inc on the next one. You double the number of rows between the inc rows all through the length of the shawl.
