I used to work at a florist, and the way they would make garlands for the flower girls (to wear on their heads) was this way:

1. Take pipe cleaners, and hook them together to the length you want.  To do this, make a small loop at one end of a pipe cleaner. Insert the end of another pipe cleaner through the loop, then loop it around and twist the ends so the two pipe cleaners are now connected securely. Continue until you have the length you want (for a flower girl's head, 2-3 pipe cleaners).
2. Using floral tape, attach the flowers to the pipe cleaner. Cut the stems of the flowers short, maybe ~ 1" long, so you don't have too much bulk, but you have something to attach the floral tape to. If you've never used floral tape, you have to pull it a little as you go to make it sticky, but if you pull it too much, it will rip.
3. Continue adding flowers (or other decorations) and attaching with floral tape until you're done. Once you've added a flower, add the bloom of the next one close to the bloom of the first one so you don't leave too much room between them (unless that's the look you want). Leave the garland straight if you're going to hang it up, or wrap it in a circle if it's going on someone's head. The wire in the pipe cleaner will give it all a little stability as well as the ability for it to hold its shape if you reshape it.

Hope that helps!
