This one’s ours. I know you said you looked at Etsy, but there’s a lot of different styles on there. What kind of rope are you looking for? They have tighter celtic knot ones and looser ribbon style ones. Most handfasting rope sellers allow a completely custom option so you can pick your colors and charms.
I bought mine from Etsy, custom made with our colors, but have you thought about a mom and pop shop that does quilting in your area? There's always a specific fabric store too. I do like shopping at AC Moore if you have one of those.
