Fabrics are generally sold in the market, and the colors are dazzling. You can search on Taobao to see if there is any.
I used to buy my own cloth to make clothes, and I have seen this kind of cloth in the cloth market. Now I open a shop on Taobao to sell cloth. The name of the store is "Golden Mango Fabric" or "Beauty Cloth House". You can go and see it sometime.
You can contact me if you are not in a hurry, and I will go to the market to help you find it next week.
