Or whatever you want to call it. The wire on my mouse is too long for my small desk, and was always getting 'caught.' So I made this big flower thing to hold some of it. The petals are sewn wrong sides together, then pinked. The middle of the flower is two pieces of felt, stuffed.
I cut enough petals to sew around one circle, each with a little pleat to give them 'shape.' Then I sewed a piece of elastic across the back of the second felt circle. I sewed this to the back of the flower, with a little stuffing inside.
You get the size of your flower by folding up your wire. You want the flower to hide it. The elastic holds the wire nicely.You just have to let out however much wire works for you.
