I would do a google search and see if anything catches your eye, then refine it!
I searched bouquet roses, then click on the blue (there is also a teal) colour filter on the side. I love the colour filter for wedding stuff! This took me all of 4 minutes to do, so hopefully it helps you get some ideas! (Personally,I like the 3rd and last bouquets the best )
I love roses and all shades of blue... Any ideas? I need help!
