Well I have made the base for them and here it is--well one of them anyway.
I had thought of several ways to use the ribbon but in the end decided on this technique.
I chopped the ribbon up and placed it between sheets of Solvy and stitched like crazy and here is the result.
You are now going to have to wait to see what I have done---they are finished but I'm not showing you yet.

Several people had suggested doing embroidery with the ribbons i.e French knots etc but unfortunately it was not that sort of ribbon.
It was more like a stiff paper ribbon and was not very flexible so in my mind it needed to be made into a base fabric.
Come back soon to see what I have done.
