I have an obsession with drawing borders around everything in my sketchbooks. Below is what the inside of one of my idea sketchbooks looks like. Sometimes I will write comments or ideas next to the pictures. At other times it is purely just images.
My favorite picture on these pages is the one of the beer
bottles wearing the jumpers.
The images above are of my zip up bag I use. It is made of plastic but is
reinforced with an internal mesh so it is very strong.
