Supplies: Fabric floral stems, an old cardigan, felt the same color as your cardigan.
Pantry Supplies: Scissors, needle + thread.
First, cut out the base of the collar. You'll measure it against the cardigan to make sure it fits perfectly. Next, pick the flowers off of the stems and begin sewing them onto the collar. Fill the entire collar with flowers until the felt is no longer visible. Lastly, hand stitch it onto the cardigan! The main reason I hand stitched it was so that it would be an easy removal once the end of summer rolls around. But it would definitely still be removable if you machine stitched it instead.
