I found the 14" embroidery hoop at Michael's for under $2.00 & the clothes pins were 25 for about $2.50. A very inexpensive craft.
Starting at the top and going clockwise, I hot glued the pins spaced 2" apart. The first one facing outside the next facing inside - then 2 facing outside around the hoop for 18 pins.
I attached a decorative ribbon and it was done. I'll reuse this hoop for Christmas cards when the holiday comes around again, but until then I've Got Mail!
