It seems I spoke too soon. For some reason, the "leaves" looked like blobs. I suspect my needle size might be too large, or the stitch patterns too small. Whatever the reason, the turquoisey alpaca yarn is now all wrapped up again in the statsh, waiting for more reliable inspiration. I think maybe a think honeycomb or stitch pattern might do the trick, but I'm going to wait until I can go to the library and check out a couple of knitting books.
So instead, I cast on a different scarf. Of very bulky proportions... Size 11 needles, and it has rows of wrapped stitches, so I think this will be done very quickly. I need some knitting progress!
