Yeah, I saw that article. We were thinking about a ringwarming but the handfasting is so doctor-who for us. We're using my grandmother's old tablecloth (she passed away a couple years ago) for my chuppah cover so we have something old in that sense. We're currently thinking of just going and picking out some ribbons in colours we like, and we'll be practicing with plain navy grossgrain this weekend with our officiant.
Personally I did a ringwarming, but I love all unity ceremonies You could get ribbons in your fav colors, or in your birthstone colors. You could use plain chord or something else neutral. Do you have some fabric that would be sentimental, like a part of an old shirt or blanket that belonged to a relative, almost like a "something old"?
I haven't done one and I don't plan on doing one - but hear me out lol
I have seen it done with ribbons that are provided by the church as well as a simple ribbon or garland that just happens to match the wedding colours / theme.
Personally I like the idea that since you have a dog that you could have a ribbon that is say red and a ribbon that is blue and together they make purple. If your dog is at the wedding then he/she could wear a purple bandana or bow tie or something That would be cute.
