I've been collecting vintage and replica handkerchiefs for a couple years now and I've seen so many gorgeous things to make with them...
If I wasn't married already, I would definitely make Save the Date cards on them, maybe for a baby blessing in the future (No, that's not an announcement)
I've thought about doing this as well, but I've got shutters in my house and it wouldn't really work.
These pillows are darling,
and you can't go wrong with bunting
or a table runner.
Framing them is simple enough,
Or do what I did, and add them as an apron to a skirt for your munchkin.
