We occasionally make baby breath halos for flower girls and I have always used paddle wire and wrapped pieces together to make a garland to start, you develop a technique to this over time. Doesn't take that long to do but it would take a butt load of BB to make all that garland. I think I used a half a bunch just to make a halo and charged like $35 for it. We sometimes used greens but most of the time not, no greens would give you the look you see in the picture, it can be made as thick as you want by using more bb even without the greens. I would think you could make a long garland and then pin it in place on a foam wreath, it has never wilted on us so no need for the foam.
