Diseño de patrones de superficie: creación y usos

A SKETCHBOOK, preferably mixed media. You can get a great spiral-bound Canson sketchbook for about 5.00 from Walmart; blue cover with a large XL in black - I use the 5.5" x 8.5" half sheet size. Strathmore also makes a mixed media sketchbook, and Michael's Arts & Crafts has daily 40% off coupons. 

A PENCIL, optional, mechanical or otherwise. Whatever is comfortable for you. I use a mechanical pencil with blue lead, no erasing! Amazon sells the blue, non-photo blue leads for mechanical pencils in both .5mm and .7mm sizes depending on your needs. You can usually find regular wooden stick pencils in blue lead in the drafting section of your local office supply store.

A PEN of your choice, black ink. A black, water-resistant fine line pen works best in case you want to add color later. I use Sakura Micron pens in the 03 (.35mm) and 005 (.20mm) sizes, which can be purchased individually at Michael’s, Walmart, or online on Amazon or Dick Blick. Fine tips and Micron pens are good for detail, but if you like thicker lines .7mm is also good. Stick pens are more reliable and less blotchy than retractable.

SCISSORS with a good sharp edge for cutting your sketchbook pages.

Watercolor, markers, crayons, colored pencils, watercolor pencils...anything for adding a little color if you want.
