How to Draw a Spider Web
To draw a spider web, start by drawing a cross with 2 lines of equal length. Next, draw diagonal lines through the center to divide your web into 4 to 8 equal sections. Then, connect the lines with inverted arcs, or curved lines, from the inside out. When you reach the end of the web, elongate the diagonal lines to make the web look like it's hanging from something, like a tree or shrub. Finally, draw a spider in your web by making a fuzzy ball with 8 legs.
Take your pencil and on the top of the page, about two inches from the right start drawing a line to 2 inches (5.1 cm) below the right top corner. The line should loop down and have points. (see the picture) Draw straight lines from the points in your first line to the corner.  Make lines parallel to your fist line going all the way up. You should have 5 or 6 lines. Get a paper and make a cross on it, try to make both lines a similar length (using a ruler will help)
  Draw diagonal lines through the centre, dividing the paper up from 4 to 8 sections. Make sure they are smaller than the cross you made before. Start connecting the lines with inverted arcs, this is an arc ), from the inside out.  Once you have reached the end of the web, elongate the diagonal lines, (this will make it look like it has supports).  Draw a spider by making a fuzzy ball, then drawing legs (eight of them) on your web. Or see the spider drawing tip. Finished.  Draw a circle and draw a cross section which also extends outside the circle.  Draw two diagonal lines at the midpoint of the cross-sections which form an X-mark.  Draw squares which descend in size as it nears the centre point. Draw the corners or vertices of the square along the diagonal lines. Draw diamond shapes descending in size as it nears the centre point. Draw the vertices along the lines of the cross-section. Draw curves to connect the lines – from the squares to the diamonds, much like forming bridges.  Trace with a pen and erase unnecessary lines. You may add drawings for spiders. Color to your liking!
