Cut a rectangle that is smaller than the width of the wrist. This is what you will glue your flowers to. Then, cut a second rectangle that is a little smaller than the first rectangle.
Pick out 2 main flowers (round rosettes) for the corsage, these will be the faux corsage focal point. Remove the roses from their stems then cut them flush at the bottom of the flower so that the bottom side of the flower is flat.
Start adding smaller florals around the main flowers. Don't glue anything down just yet.
Once your'e happy with the floral placement you can attach the accent flower stems together. Basically, make double-ended floral stem. These do not have to be identical. Then wrap the middle of the double-ended floral stem in green floral tape to keep them together.
Next, placed them on the bigger rectangle to see where exactly you want them before hot gluing anything down. This is the time to trim your felt down if you need to.
Now, use your glue gun to glue everything to the felt. First, glued down the double ended floral, let that dry so that it gets secure. Then I glue down the main focal point flowers, the round roses.
Fill in the gaps where the corsage seems to be bare. You can cut down larger florals stems and leaves to add in for filler. Add a dab of glue to the ends and place it on the corsage.
Once you are happy with how the cosage looks and the glue is dry you can add the hair tie to hold it onto the wrist. You want to glue the hair tie onto the corsage so that the corsage lays vertically against the wrist. In other words, glue the hair tie so that it sits on the rectangle horizontally. After that glue has dried add the second rectangle on top of hair tie so that the hair tie is sandwiched in between the two pieces of felf. This will make it extra secure and the most comfortable option for wearing the corsage.
