This is just so creative.  Silk tulips are in abundance in spring in most craft stores.  I would probably suggest buying the ‘bunch’ variety and a few singles for length to make it more economical.  I will definitely be making this for myself, maybe mixing up with a different bow or such.  I will post my results when I am able as I am still house-bound in recovery from my accident.  Have you tried this?  I’d love to see your results!
