Okay. What am I going to make out of the ribbon yarn?
I found several patterns for tops made out of ribbon yarn. But very few with the same yardage per 50 gram ball. So that has narrowed it down substantially. I found this:
The top is called Badia and is made with a braided cable, not ribbon, but the weight/yardage is very close. The pattern is located on the Berroco website.
So, unless I run across something else between now and the time I finish a pair of socks I've started on...this is it.
