I simply cut out inexpensive muslin to fit the embroidery ring, leaving a 1 inch border.
I taped down the muslin to the inside ring with a little masking tape... then painted on chalkboard paint.
I painted the outside ring white then put the embroidery ring back together. That's it!
So I'll be back later after we're upgraded to FIOS... hopefully by Sunday. Verizon has been a miserable disappointment, so my expectations are lower than low. We may need to go back to dial-up, "rabbit-ears" and smoke signals. ;) Wish us luck!
