You're going to get a kick out of this one -
Ok, I took your kind suggestions to use a 'heavier than lace weight' yarn for my first project and I cast on with beautiful Weavers Wool Quarters (Ruby River colorway). So, I'm knitting quite happily along and making excellent progress, if I do say so myself, when I go back and take another look at the pattern. . . more closely than I had before, I guess. You know what? This shawl is in st st, not garter stitch . . . oops! And I was following the chart so well, counting my stitches, placing my markers; what a goof! If it had just said somewhere - THIS SHAWL IS KNIT IN ST ST - I would have automatically purled the wrong side rows, excepting the edge stitches. Oh jeez.
It doesn't look bad, just different. But what to do? Continue as is until the next chart, then switch to st st? Maybe run a lifeline and try a repeat in st st and see how it looks, then decide if frogging is worth it? Any sage advice?
