You can get what you need from most FINE ART supply stores (NOT crafts stores like Michaels/Hobby Lobby) and the items below
are usually displayed together. They are all "block printing" supplies. Call first to see if they have the first three of
the following in-stock:
Roller: The roller is called a brayer and you want one that is hard rubber. Minimum of 3 inches wide (7.62cm).
Ink: Speedball Water Soluble Block Printing Ink in black. Colors stain the hand. Outside of the US/Canada you will need to find the equivalent.
Linoleum: This is the surface you roll the ink out on to coat the brayer. 4 X 6 inch size is perfect for 3 inch brayer width.
The three above fit well into a large Ziplock bag together.
Paper: You can use any type of paper that will take the ink. Standard copy/laser paper works just fine.
