TIPS |
Recommended Paper for Drawings
• Clear plastic film, such as acetate, overhead transparency.
Note: Do not use heavyweight card stock papers or premium computer printer papers.

Drawings
• Drawings must be black and white only, no gray tones.
• The most important trait in a good drawing is to make sure it is very opaque (very dark). The higher the opacity the better.
• When tracing or drawing your own artwork, make sure to use an opaque pen.
• When using computer printers, setting the printer for premium inkjet/laser paper usually results in better opacity. However, do not use premium paper.
*Tip: Reinsert your copy into your printer several times to produce a very dark image.

Recommended Paints
Thick, slow drying paints work the best. Thinner paints can be use but require some practice to produce desired effect. Do not use runny paints.
