So I really really love light blue, like a mix between sky blue, and aqua blue. soooo I was thinking about doing both shades of blue, with cream and gold. Will that really look right all together?  I already bought some cream flowers from efavormart, but I dont really know if I should do blue roses, although they are fake, I want to give the illusion they are real, and I dont think blue or gold flowers will fly, what does everyone else think, I have to go back to work, but I'll upload pics of my vision(look im going for) to this post on my next break
