Paper Material (fiber):
- Cotton - highest grade and ost archival. naturally acid free. longest and strongest fibers making it extremely durable.
- Cellulose - low to mid quality. typically student grade paper with the shortest fibers. (Newsprint and construction paper are both made from cellulose) these papers are more acidic and not archival and will break down over time.
- Combination - mixture of wood and cotton fibers. generally used as a multipurpose paper.
- Tooth - surface texture
- Ream - 500 sheets of paper
- gsm - grams per square meter
- Sizing- starchy glue that binds and strengthens paper. helps paper be more resistant to moisture absorption. paper with both internal and external sizing is best and allows for richer color saturation. It is also more durable for reworking, lifting and scrubbing. less permeable paper.

Stretching Watercolor Paper:
- the paper can be clipped onto a board for support using binder clips.
- Most artists prefer to tape the paper on all edges to hold it in place and give a clean, white border when the tape is removed.
- If you enjoy working on larger sheets of paper, or more lightweight varieties, stretching paper is a good skill to learn.
- Stretching steps
- soak paper in clean tub for 10 min.
- holding two corners and tipping the paper, drain off as much water as possible.
- lay the sheet on your support board
- once paper is flat, use a staple gun and place a saple in an upper corner. gently pull the opposite corner tight but do not overstretch. Staple that corner down. do the same for the other two corners, again taking care not to pull too hard. then add a staple in the middle. be sure to put the corner staples first then the middle ones.
- make a 1:1 mixture of wood glue and water
- using brown paper packing tape, torn to fit each side of the paper, wet a strip with the glue mixture and stick on watercolor paper/board overlapping about 1/2" Press in place. repeat for all sides.
- put staples every 2" on top of the brown paper and let it dry flat.
- To leave clean edges when the painting is done, use 2" white artists tape, again overlapping the white paper by 1/2"
