I ended up stuffing the ornaments which proved to be challenging when I put them in the mail. Most came in at a reasonable price for postage but one came back with an “Insufficient Postage” sticker (sorry about that Trevor).
I took that particular card apart and used batting in the centre. I debated about doing some quilting on the front but I decided it didn’t need it. The card is flatter but stuffed with just as much love!
