Prep and gather your supplies. You can see we mounted our pop riveter on a piece of wood so young kids can move the lever. The aluminum is thin flashing aluminum from the hardware store.
Take a piece of paper and draw out the shape of your cookie cutter (we cut the paper into 5 1/2" x 5 1/2" squares to limit the size of cookie cutter shapes).
Take an aluminum strip and tape over one edge of it with masking tape.
The easiest way is to line up the middle of your tape along the edge - then you can fold it over to the other side.
The masking tape is for making the cookie cutter safer to press down on.
Take your cookie cutter design and your aluminum strip.
Carefully bend the aluminum strip into your cookie cutter shape.
The gloves will make it safe to handle the sharp side of the aluminum.
When you are ready to connect the ends of your cookie cutter together, take a hammer an awl and a piece of wood to hammer on.
Hammer the awl in two places across from each other on your aluminum strip.
Make sure the dents go through to both sides.
Take the hole puncher and punch out the holes you made with the awl to make them bigger.
You will need two pop rivets for your cookie cutter.
Push one pop rivet through one of the holes. Careful not to put the pin side through the hole - you need to push the rivet end through.
Slide the pop rivet machine over the pin, close the handles until you hear it "pop" to complete the rivet.
Now take another pop rivet and push it through the other two holes. If the rivet doesn't fit you can use the awl and wiggle it around to widen the hole.
Again squeeze the handles until you hear the "pop"!
If there is excess aluminum you can use utility scissors to cut it off.
Tape down the sharp edges.
Check the shape and fix any bends you want while you have the gloves on.
Make sure you wash your cookie cutter before you use it, and start making cookies!
