Gather your cans
cut the two colored cans (not green) into shapes of petals.
cut your green can into the shape of a leaf and a longer, skinny piece (the stem)
Take one of the tops of the can (where you drink from) and cut that off the can.
hot glue the petals to the top of the can - you can layer them and make them a lot cuter then I did.
attach the leaf to the stem- and the stem to the back of your flower and VOILA!
the edges will be sharp on your flower so glue the sides of everything and/or tuck over the edges
