1 option how to draw the open book in firm cover (a firm cover).
Step 1. We draw a vertical straight line, then we draw from it curved lines in both parties from above and from below. Then from below by a straight line it is drawn, as if a droplet, then we draw the same curved lines from below and we draw lateral straight lines.
Step 2. We draw from below the bent lines straight lines, then we draw a cover at the book, we paint over a pencil dark sites.
2 option how to draw the developed book in soft cover (a soft cover).
Step 1. We draw at first a vertical straight line, then we draw oval curves in both parties from above and from below a straight line, then we draw the straight line connecting these lines, two leaves of the book turn out. Then sideways these sheets we draw sheets which are under the top.
Step 2. We draw still sheets which are under the main, then we draw a soft cover at the book and we paint over it a pencil.
3 option how to draw the closed book.
Step 1. At first we draw the turned rectangle, then down from two corners we lower vertical straight lines identical, then we draw parallel straight lines, we look at the picture and we copy. Then we draw a rim, too lines have to be parallel each other, in the book, the showing cover.
Step 2. We draw straight lines as on the picture, then we paint over, we erase very small line at the corner of the book from below.
