Once that was done, I cut the pieces to the proper length for the sides, fronts and backs. I then laid the drawers out so I could mark them for dovetailing. Each piece is placed up side down and inside out and marked, so when I dovetail each corner it turns out right. I know that's confusing, but for me that comes natural (another words, it's easy for me to think backwards.) LOL.
I use the Porter Cable Omni Jig to do my dovetails. I leave one of my routers set up with the proper bit all the time to save on set up time. It's very critical to have the bit set exactly perfect to get a good dovetail. (that's why it's worth designating a router just for this function.) This router is left set up for dovetailing and never used for anything else.
