Since I work at the end of the week, I often get to take home flowers that were going to be thrown out. I've made several arrangements from leftovers. It kind of limits my choices, so some of them turn out cool, some don't turn out so great. Here are a couple that I made in the last few months with leftovers. I like the red/orange one the best. I wish the pictures showed the arrangements better.
Roses, mini gerbera daisies, yellow irises, misty blue
This picture is truest to the flower colors.
Delphinium, alstromeria, mini carnations, asters, stock, misty blue
