Hi AnnaW: we've e-mailed before about sugarpaste irises. my last attempt at these was too hurried and not very successful, but I am trying again and have some questions about coloring. you said you colored the paste first and then dusted. i'm making the dark purple ones & the falls have a splash of yellow running down the center. i'm not sure how to get more "depth" to such a dark color. i've tried starting w/dark paste, but it just looks flat. any advice for this? also, what about the yellow? mixing the dust w/vodka doesn't give very good coverage. too translucent. any help is appreciated. thanks much!
