Wash the tin cans thoroughly. Remove all label and any adhesive residue.
Cut the cans vertically using a dremel tool with a metal cutting disk attached. (Cut about every 1/2".) Be sure to wear safety protection such as safety glasses and gloves.
Paint the cans in Coastal Waters and Paprika. Let some of the can show through for a rustic look.
Squash the can, by slowly adding weight to the top of the cans to get them to start to buckle in the middle. (They will naturally form a "V" shape.)
Using safety gloves, shape the cans: Stick a gloved hand inside the cans and reshape the "V" to make it more of a gradual "U".
Add twine or other embellishments around the top and add tea lights.
