Thanks to both of you! I will try your suggestions.
Also, regarding the dropped stitch, this was the last stitch on the row. Somehow it fell off the needle and I think I accidentally tugged the yarn, losing maybe more than one stitch vertically there. (Does that make any sense?!) I was just going to put it back on my left needle and do the stitch over (it was supposed to be a purl stitch), but it was elongated and didn't look right. That's when I decided to frog it.
I had frogged garter stitch before, and that's easy to get back on the needle. This was a different story!
