Mum embroidered some gorgeous tea towels for a wedding gift for a friend's daughter (a smallish gift, she doesn't know the daughter hugely well, but a very nice 'token'-type present). The kitchen colour was red so she found some pictures of cherries and strawberries online and embroidered them onto the towels, added rickrack and they were beautiful!
I once hand-painted a ceramic plate for some friends which they liked very much. I did it at a ceramic place using a squirty-bottle of special ceramic 'ink' used for writing and drawing lines, and I just covered the whole plate with the names of famous literary and historical 'couples', whether romantic or just people who went together. So Antony and Cleopatra, Merry and Pippin, Han and Leia, R2-D2 and C-3PO (the couple were geeks)... and then the couple's name 'hiding' somewhere in the middle.
They got divorced.
I assume they must have had some ceremonial plate-smashing ceremony or something, because who'd want to keep that
after splitting up? So, moral of the story, only make something intrinsically couple-ish if you're fairly certain they're going to stay together... and crikey, if that isn't a cynical attitude to have towards wedding guests I don't know what is.
Beastie cloths often come in handy too, and are very good for shipping - a big square or rectangle of gauzy, floaty fabric trimmed with nice craft fabric and/or embroidered (like with a few bees here and there, or whatever), big enough to cover a kitchen table to keep the flies away. You could make placemats, coasters, napkins or whatever out of the trimming fabric, to match.
