Love in material (but not immaterial)

OK, so I might as well fess up and show you that I got a wee bit silly over the weekend, and I made these for my nieces (well, I made them out of left-over wool, then decided they'd be for my nieces). I haven't sent them yet, so they are not exactly Valentines, and they'll know they're from me, because who else sends them crochet, but hopefully they think it's fun (and I'm wishing I'd been a bit more dramatic, and stolen a line or two from Mr Darcy, but, you know, better not to overdo it, lest they think their Aunt is a complete nutter). These envelopes are cutely small, and it's not so easy to write on little scraps of fabric!
