Do you have any advice on how to deal with paper warping?
The paper getting sobby and uneven often quickly brings a painting session to an end :)
And yet in tutorial videos I often see people paint a whole background section in one go (even as much as half the page) without any issues. Do they glue the sheet down to a board?
1) look up videos of "watercolor paper stretching" on youtube, and clamp the paper down if you can (I'll tape all way around a sheet to make a nice border anyways).
2) alternately use watercolor paper blocks (which have adhesive on all sides of the sheet, which minimizes curling)
3) get heavier paper (thicker), use less water, and don't let water pool anywhere.
