Here is one idea for a DIY portfolio case. For teaching 12-14 year olds check out the art ideas section of the blog and look for ones tagged “secondary art”. Also keep in mind this age group is obsessed with realism and can become discouraged if they fail at drawing. Stick to more abstract projects first to boost their confidence and slowly introduce more realistic concepts later. Keep a look out on the blog in the next couple weeks for more secondary art ideas and drawing tutorials!
