You will need:
1) a sheet of paper (small, abt 3x3 inches).
3) pens (feel free to make it colorful)
4) 1 toilet paper roll
5) a scissor
6) a way to mark circles (free hand or with lids as I did with the Pringles lid)
Step 1: Marking and Cutting the Target
Step 2: Make the Base for the Target
At the bottom, cut the front and the back of the base as shown in the picture. This doesn't need to be accurate. The purpose is to let the target fall easily once hit by the arrow, so you will need to try with your fingers simulating the hit.
Step 3: Glue the Target to the Base
Note to glue it on the front of your base, eg where you did cut the base to make it easier to fall backwards. See the picture.
Now you are ready - have fun ! ;)
