Thank you for your responses. I had thought of both of these methods and was wondering what might work the best ! Like many knitters/crocheters, I'm somewhat allergic to sewing (I get large, feverish I-don't-want-to's when it comes to sewing--they're really quite awful), and the thought of doing a simple stitch around two pants legs . . . well, that just might be a bridge too far!! And then what would I wear--okay, well, cut off, raggedly looking capris!! Ugh!
So I might try the crochet method (somehow life's better with a crochet hook in your hand rather than a sewing needle--I don't really understand this, but so says my little pea brain)! HOWEVER, it's always good to have a Plan B (even if that plan makes you want to hurl . . . . something across the room)!
