My (not so little any more!) sister's senior prom was this past weekend, and I got to make boutonnieres for her and a friend's dates. Hopefully I'll get some pictures of the young gentlemen modeling their boutonnieres, but until then here are a few pictures of the finished products:
Red rose boutonniere with black ribbon - to match a red dress
White rose boutonniere with turquoise ribbon and sheer silver ribbon overlay - to match my sister's gorgeous turquoise dress!
Several years ago I worked in a flower shop during prom season and made definitely over 100 boutonnieres in about 24 hours... I think my fingers are still sore from all the wiring! But I got lots of good practice!
I also really like ribbon wrapping the stems on boutonnieres - I think it gives them a more finished feel, and a better look. I also like wrapping with lily grass, twine, or other things. It ties in colors/styles well, and looks a lot better than just floral tape.
