Summarize this article:

You’ll want a container large and sturdy enough for your particular purpose that includes a plastic lid, like a can of nuts.  Empty the container of its contents. Wash and dry the inside. Using a flexible measuring tape or ribbon, measure the container so you can wrap it with the right amount of paper or fabric.  Measure the circumference of the container; write down the measurement, adding one or two centimeters for overlap allowance.  Measure the height of the container and write it down. This is what will turn your can from a boring food container to an attractive, personalized money box.  Choose or cut out a piece of paper or fabric large enough to wrap all the way around the container. Lay the paper or fabric face-down on your cutting surface. After tracing out the rectangle, cut it from the paper or fabric using the outline as a guide. Once the rectangle is cut, wrap it around the container to make sure it fits properly. If it’s too large, trim it down to size. If it’s too small, begin again with a new piece of paper or fabric. Before securing the paper or fabric to the container, lay it down right side up and write or draw any of the decorations you plan to use. It will be significantly easier to perform this step while the paper or fabric is lying flat than when it’s wrapped around the container. After the paper or fabric is secure, add any additional decorations you may want. At this stage, you can add decorations like buttons, ribbons, jewels, etc. Use hot glue if the decoration is heavy or won’t stay in place with regular glue.

Summary:
Find a suitable plastic food container with a plastic lid. Measure the container. Choose the paper or fabric with which to wrap the container. Cut out the rectangle. Add any decorative writing or drawings you want to include. Add any additional desired decorations.
