Sorry for taking so long, maybe you do not need the symbol now... but I found one on "AmazingDesigns.com" right at the top of the free designs page...hope it helps out..
There is one here for free.
thanks, it is a very nice one, but it is big
Aunty's is 1.5 inches. That's the smallest I have.
here is a design for free, the size is 78 mm so it's bigger than you want . but perhaps you can make it smaller.
