That is a beautiful bag. I have only made 1 mini bow tucks but sold it as well as a lot of the large size. I was selling them for $45.00 plus postage. The person who bought my mini was happy to pay the same price as everyone else because she wanted it for her daughter.
I have checked the conversion chart and USD & Aud are almost on par at the moment. But I think with your beautiful embroidery your bag is worth more. Good luck.
