stiff red or black felt
To make this, I used the same method I did when making the Rosette Necklace. Start by ripping the black material into strips. Then tie a knot it the end of a strip and start twisting and wrapping around it, hot gluing every so often.
For Minnie's bow, I simply ironed a strip of the red material into a ribbon, folded it and tie it in the middle.
After the bow is made, trace the Minnie Mouse head onto the stiff felt and cut out.
