Simplified coloured pencil/watercolour technique in textbooks

On the web you can find hundreds of sites full of info regarding tricks and techniques.

Lots of illustrators meet and share insights. Below there is a typical example...

"Do you simplify your colored pencil/watercolor technique somewhat when you have a textbook assignment?"

Believe it or not, I started adding watercolor into my colored pencil to SAVE time! As well as add color saturation while avoiding carpal tunnel syndrome. I like the look better, and an intelligent underpainting gives you a great final look. I guess I just shift the ratio more towards paint when I am in a hurry, but I usually end up with the same look each time. And am growing more painterly lately, as well. Plus, I can spend as many hours or more working up roughs as doing the finals. I cannot possibly imagine how you can (pardon upcoming pun) cut corners on paper sculpture, either!!!

Skip -- About the warping watercolor paper, recently I tried a light water spray on the back of my curling piece, then surrounded it with white paper towels front and back and heaped weights on it for overnight. Very flat the next day, and no ironing! kt. -- Ironing Artwork I used to always go to the trouble of stretching my watercolor paper by soaking it in the bathtub and then taping it to a board. This was to keep it from buckling when the painting was done. Instead, try ironing the finished art!

Set the iron to it's highest setting... linens / cotton... and when it's hot... spray the back side of the finished painting with two or three brief sprays of water from a spray bottle (taking care not to get any on the front side!). Then place the art front side down on a clean sheet of paper. I use railroad board, and build up a base beneath it of old cardboard from the backings of paper tablets. A short quick ironing will remove nearly all the buckling from the art... (leaving only s slight waviness) Voila! It's ready to send off to the publisher! I've used this on both watercolor and acrylic paintings... without disturbing the image in any way.

What is gesso base technique? I do really detailed watercolors and any info on preserving it as I work would be appreciated. I've been using a light fixative over pencil and watercolor in between layers ...Payne does that...but options would help.

Sometimes I'll give 140 lb. Arches or illustration board a couple of coats of gesso, then use the watercolors on top of that. It's fragile, you can remove them with a damp rag, for instance, or you can take up some of the color, but not all. So if you don't like something, you can still fix it. Seems to work better on a smoother finish, but I've used rough paper too.
