I like the hearts. How fun!

I like the rose print, but I know it was way too busy. I can't decide how you would use it. I do like what you are doing now and I can't wait to see it finished, it will be beautiful.

I like the 3rd one! It has pizzazz!!!!! :)

Personally I'd go with the floral. To me the hearts take it too much into Valentine's Day. A tone on tone red floral might be a better choice. It would be almost solid and let your embroidery blocks pop but still have some texture and design.
