subject: How to Divide your paper for smaller paintings ? [print this page] You can divide a half-sheet in half to make a quarter sheet and keep dividing for miniature pictures. Do you have to divide the paper evenly in halves? Of course not. You may want a thin vertical painting or a long horizontal painting, or you may want a shape other than a rectangle. Anything goes in art. Many of the exercises in this book look nice on a 1/16-sheet (or 5-x-7-1/2- inch) size.
