Dear Tom,

　　How are you doing?I wonder if you could sell some Chinese knots for me. I made them myself with red silk threads, cloth and other materials. They look really beautiful in the shape of a diamond, about 5 inches long and 4 inches wide. In China, these knots stand for friendship, love and good luck. People can either give them as gifts to friends or hang them in their houses. They are only 12.99 US dollars each. If anyone wants to know more about the knots, let them write to me. Also, do let me know if you need further information. Thank you!
