Fill a larger bowl or the sink with enough water to submerge the football shapes in. Take your two football shapes and crinkle them up in loose balls. Put them in the water and let them soak for about a minute. Once you take them out of the water, open them up and lay them out flat to dry. Don't press them too flat though, you want the "wrinkly" effect to look like the tough leather of a real football. At this time, you can use the brown watercolor paint and brush it lightly over both football shapes (on the side that will be facing out, which is the blank side if your bag has writing on it) to add some shading.

Once your football shapes are dry, take one of them and set it aside and take the other one and use the hole puncher to make two rows of holes towards the top edge. Like This:

Cut enough pieces of white yarn to string one piece through two holes. (If I had the football shape above, I would cut 6 pieces of yarn about 4 inches long.) String the yarn through the holes as pictured below, and secure the ends with tape on the underside of the football shape.

   

Once this is done, you are ready to staple your two football shapes together and stuff! Fit the two football pieces on top of each other and make sure you have the correct sides facing out. Attach them by stapling around the edges, leave a 4 - 5 inch opening along edge. Take your left over paper bag from the first step and tear small pieces from it, crumple them up, and stuff them inside the football. Make you you do not over stuff it or else you will not be able to finish stapling it closed! Once you are done, staple up the opening.

Your football is now done! You can tape or staple a longer pice of yarn along the top edge to hang your football if you want. You can even make smaller versions and attach them to a piece of magnet to hang on the fridge!
