Choose a corsage ribbon that is narrow and looks proportionate to the size of your final corsage. I generally prefer #3 ribbon, which ranges from 5/8" to 9/16th inch width.
This particular ribbon has a sheer center and a satin edging.
It comes in 11 different colors and is a beautiful accent to any corsage. I like it because it has enough stiffness to make a crisp bow. Too limp of a ribbon makes a droopy bow that is hard to work with.
I use light colored or white florist tape for covering the wire used to secure the bow. Green tape can show up in a sheer or light colored ribbon and isn't as easily hidden.
Start at the top and pull gently in a downward motion while turning the wire.
You may want to make up several of these ahead of time, snip in half and have them handy when you are ready to make your corsage bows.
