Dear Ginni,

How are you getting on these days?

I wonder if you could sell some Chinese knots (结)for me. I make them myself with red silk thread, cloth and some other materials. They look real beautiful in the shape of a diamond, about 5 inches long or 4 inches wide. In China, this knots stand for friendship, love and good lucky. People can either give them as gifts friends or hang them in their houses. They are only 12.99 dollars every.

If anyone wants to know more about knots, let them write to me. Also, do let me know if you are need further information.

Thank you !
