Why not tie on longer piece in the center & then just curl each end I think you need to knot it on as it could slip & get messy if pieces start falling off. It must be a double wire wreath to get it that wide.

I would do it bundles - curl long pieces, gather them up to a nice size and tie them into bundles using another piece of the ribbon. Then tie or glue them to the form.

Cute wreath idea!

I make the yarn wreath where you use a hanger shape it nto a circle,make bundles try a few till you get the legnth you need,After you get all ribbon on then curl.I myself dont like all the footballs,at craft store they have all kinds of wood things.
