Materials Needed:
Cut one of the dowels 21″ long and keep the other dowel full length for now. Take the 21″ dowel and center horizontally it onto the larger dowel 9″ down from the top of the longer dowel. My dowel ended up being 10 1/2″in from the sides when centered. Secure the dowels in place by wrapping string or ribbon around the dowels in the middle. Make sure that they make a straight cross and are as even as possible.
Take and lay your garbage bag flat on the floor. Place your cross on top of the bag. You want the top of your cross to be even with the top of your bag.
Mark your wooden dowel where you want to cut the excess part off. I wanted to cut the drawstring part off from my kite, so I measure just above where the drawstring area stopped and cut my dowel there.
Cut the dowel with a pair of sharp kitchen scissors. Should look like this now.
Take some duck tape and tape it around all of the edges of the dowels. This will keep the dowels from making holes into your kite. 
Now lay the cross onto the bag. Measure to make sure you have it evenly spaced on the sides and as close to the top of the bag as possible. Tape the dowel in place at the edges of each of the dowels. 
Now take and fold the top edges of the garbage bag in. Try and keep them neatly folded and even. Place tape on the front. 
And fold it over neatly, like so. 
Repeat with the other side of the kite. 
Your kite should look like this now. 
Cut off the drawstring part if your bag has one. 
Tape the bottom of the bag. 
Tie some ribbons onto the bottom of the kite.
Tie a piece of string or ribbon onto the kite just above the center of the cross.
Wait for a windy day and enjoy! 
Hope you all get a chance to stop by my blog and take a little peek. Thanks again Becky for having me here today!
This is great! I’m going to try this out with my son. It doesn’t look too difficult.
