To see more how to draw worksheets like this search the sidebar.There were hundreds of designs in ancient and medieval times so you can make any changes you want.Tip: to add realism in your drawing make sure the lines are parallel on the post, brace, wagon, arm, etc.Start by drawing lightly so you can erase later without damaging the paper. Draw a rectangle for the base of the wagon. You are drawing it from an angle so be careful to keep those lines parallel. Next, draw circles for the four wheels. You might trace around a lid, a jar, or a coin to make the circles a round shape.Draw the two posts that hold up the throwing arm. These posts are like tall skinny rectangles but use the third line to give the side view and dimension. Draw the arm and the brace the same way. Use short choppy lines to give the wood grain effect.Draw a second circle around the wheels for the iron rims, and a little circle in the middle for the hub. Add lines across the wheels for the wood grain. You can add nails or screws around the rim.Draw the chain in steps. Outline it lightly then go over it darkly for the iron.Draw the rocks as a bunch of circles then add rough edges to the circles, finish the rocks with dots and dashes so they look rough and ragged. Put grass all around, and remember to add shadows underneath.In the example below I added a few extras like a chain holding the arm down, and an iron bar across the deck of the wagon and on the side. You can add your own touches like spikes or armor or weapons, maybe a soldier sleeping against the wheel.
