You should definitely do something...GREAT grands? Wow. Congratulations!
I've done labels using my embroidery machine but feel like more or less a newbie when it comes to labels. I just buy a ready made border and fill in the middle with words. Some here just use pens, but I know from a quilt I was gifted that after a few washings, those "permanent" markers start to get light--one of the original reasons I was interested in an embroidery machine.
Here are a few of mine. a memory quilt for a Polish girl,[ATTACH=CONFIG]431361[/ATTACH]

Most of the charity ones I do just a simple one saying the name of our organization and the address--one color.
