Step 1: Main Frame

The frame is made of 7 of these three-connector units.

Step 2: Handle/Grip


Step 3: The Cross of the Bow

First take the last unit of the frame and attach a yellow rod to the middle connector.  Then add the white snowflake connectors on either end, after which you can put on the two other yellow rods.  Wrapping the rubber band(s) around the cross is pretty simple.

Step 4: Firing

You will need the bolt (top) and pin.  The bolt slides perfectly into the channel, and the pin locks it in place.  Then draw the rubber band to the red connector.  Yank the pin to fire.
