This might be too advanced for the little ones, we are going to use an image from one of my kids books, since it's easier for me to just document my illustrations as I work rather than do separate illustrations just for the lessons. Ok, ok.
For adults ,and kids if they wanna try, this is the image we are using for lesson 1. Just right click and save image to your desk top and print this if your using a light box or want to sketch it.
Part1 basic over view of simplest choice of tools and supplies to get started. A light box is optional, If you want to sketch by hand go ahead. If you aren't that good at sketching just start with a light box, it will help you along. I use a light box because I am doing so many illustrations it saves me time.
In case you cannot read the subtitles here is a basic over view:
Use quality paper, Arches or Canson. Arches is cotton rag paper so it is very durable and can handle alot of abuse. Cheaper paper will not be able to handle removal of masking tape, and you will ruin your finished painting when removing masking tape. For children disregard this info as they will need to blast thru alot of paper before developing skills.
Use quality masking tape NOT bargain brands, they will leave behind an adhesive residue on your painting and ruin it. Scotch brand is fine. And the blue tape will not adhere properly to paper so do not buy the expensive blue masking tape.
For kids bargain paints are a good idea. If you cannot afford a brand like Turner gouache or Winston just get what ever you can afford and as you develop your skills you will appreciate higher quality products. As you learn you will notice cheap paints have lots of binder which will dry funny, quality paints have more pigments that are higher quality so you can get those intense saturated colors. Also I use gouache instead of watercolor tube paint because it is very concentrated and a little goes a long way, they will last you for years if cared for properly.
