Wholesale Markets Where the Professionals Shop
I used to spend hours looking at decorating magazines, envying all the rich and successful homeowners who could afford to buy the most beautiful and most expensive furniture, decorate their homes with the most unusual wall coverings, and drape their windows with the most beautiful fabrics.
I would wonder how in the world, or more importantly, where in the world, did they find such unique items for their homes.
Now I know! Most of them used the almost endless resources of the design centers and wholesale merchandise markets around the United States. Though most of these design centers cater to the professional buyers and designers, they do offer "Open to the Public" days occasionally. They're a great place to shop for something special.

Another way is have a friend who is “in the Trade”.
They may not be able to buy in small amounts for you, but at least they can get catalogs and tell you when the Public days are.
That’s exactly how I learned to shop the Mart. A friend showed me the ropes so that when I got my license, I felt like a real pro negotiating my way through the showrooms.
Before choosing the colors, we must first know what kind of material are used to make it.
There are some toxic paints with very nice colors.
Your tip about looking at decorating magazines is great.
