SO! I need some advice here! Our wedding colors are Green and Black with a white accent, we are also using damask pattern. As of right now our table set up includes black table cloths, a white with black damask runner, and apple green linen napkins. For our center piece I really loved the "busheled" carnation look so we have small round (think tiny fish bowl) vases with a bushel of 16 white carnations over flowing. Inside the vases we will have a mixture of lime green and clear crystal mud (if you don't know what that is here's a link: http://rainbowcrystalmud.com/ ) with a submersible light in the bottom to light it up. We are also talking about doing a green ribbon/bow around the top of the vase as well. Also we have a ton of basic white candles in clear glass holders (votives, tea lights, and sticks) that will be scattered all over as well. SO my wedding planner brought me a mock up of the flowers and vase (mind you we don't have the crystal mud, ribbons, or lights yet) and she said she tried to use the green hydrangea spray on the carnations but it looked bad and really fake not that pretty flower look, and the issue we run into with the ones that are treated green is that the green may leak into the water because of the dye and that's not very appealing either. Well I loved the way it looked, its kind of like this but of course white with the ball like vase:

Here is where my issue comes in...soooo I show my fiance and his first question is why aren't they green? I tell him..... The next question is well I thought we were going to do green flowers....I explain to him that carnations are our cheapest alternative right now and that Sam's Club doesn't sell green ones and he asked me about hydrangeas, again I went back to cost and told him I really love the "pom like" carnation look and that I think its so pretty. THEN I hear how everything that was going to be green has changed and there's going to be no green and he just cant picture it and then of course I'm stressed because I'm in the middle of my mom trying to save on costs, my planner coming up with awesome ideas that I love to help with costs, and him wanting more green. (Does anyone else have a fiance this opinionated? I thought it was great at first but I think that its now more of a burden! I for sure want him to have say in the wedding but every time I come up with an idea that I love and that will save money in the end I get the look) So my question for all of you brides out there, do you think we are lacking on the green in our wedding? Our cake is white green and black, our bridesmaid dresses are green, the groomsmen vests and ties are green, my bouquet and my moh's bouquet are green and white, as well as his and his best mans boutonniere. We are going to have apothecary jars filled with cake balls that more than likely I will make predominately green. I just I agree that when i explain the table it probably sounds more black and white but I just don't know what to add so it doesn't end up tacky either? Do I spend the extra money ($300 would add 4 roses a centerpiece) and add some green tea roses to the centerpieces or does that take away from the pom look I was going for? Do I take the time to wrap the votives in green vellum paper? or do you think its just enough and hes just being a guy and I need to not worry about it? I just really need some advice because I feel like I'm being tugged three different ways right now!
