Make a roller from a cardboard tube, to print a piece of paper with. (Artist Badge)
cardboard tubes (1 each), copydex or similar glue, string, small pieces of cardboard or foam shapes, paint, paper, large trays, paintbrushes
Make a design on your roller (cardboard tube) using the string/cardboard/foam shapes. Copydex will dry quickly and strongly allowing use sooner than if you used PVA.
Either using a paint tray, or paintbrush, apply paint to the raised surfaces of your roller, and roll over the paper. You can repeat the design in different directions and/or in different colours. Allow to dry before using for another project.
