I've been creating my own patterns on fabric by silk screening them myself. I use water based paints and then heat set the inks with an iron or a hair dryer. The fabrics I have been using are vintage scarfs and scraps from a design studio I used to intern with. This animal pattern I printed on an old scarf I got from the Saturday and Sunday flea market on Avenue A and 11th street. The scarves are only a dollar from an onld man next to a Caribean food cart!
I buy my water based printing ink, Sprectrachem, at New York Central on 11th St. and 3rd Ave. http://www.nycentralart.com/
or
Blick Textile Screen Printing Ink, at Dick Blick on Bond St. between Broadway and Lafayette.
