How do you organize sales of art products such as handmade carpets,etc.?

This type of art is usually expensive so before organizing the sales, you have to set a certain targeted customer segment, by checking the area of class B+, Class A and class A+, then define their needs, then start to sell to them.

On the other hand, the open shows and the specialized shows participation are highly needed to show the customers your products, let them touch it and decide to buy. 

Finally, I recommend using instagram and pinterest to advertise about your product. Never, ever give discounts but make the promotion on a number of pieces, as when you make a discount on a product, people usually think this is the real worth of the product but when you sell buy one get one free or get a new collection with a certain price or make vouchers when you buy with xx amount, you can show the voucher to pay the rest and so on.

I hope this answers your question and i am happy to help.
