Wedding bouquet question!

Question

we are getting married the end of this month... and i still have no idea what flowers to use for the boutonnieres and corsages :( i am doing all the flowers myself, and i have ordered Gerber daisies in a white, soft pink, and yellow color. any ideas as to what to use for the other flowers? carnations? daisies? other flowers? I'm clueless/ baffled as to what to do :(
