Materials:

• T-shirt (the large the shirt, the bigger the scarf)
• Foam pouncer
• All-surface paint
• Tape
• Scissors

Lay your t-shirt flat, taping down the edges. Cut a line straight across just above the bottom hem and just below the sleeves or the armpit. This will form the actual scarf so try and make the cut edges as smooth as possible. Dip your pouncer in the paint colour of your choice and start dotting.

Stamp your first row spaced however you'd like, then make the next row alternated from the first. Repeat this step until one whole side of the scarf is pattered.
