Roll a terracotta pot over a sheet of paper, tracing around the pot as you roll to draw out the shape of the pot onto the paper.
Cut out the paper form, using scissors.
Place the paper form over a piece of fabric, then trace out the form onto the fabric adding 2 inches onto each edge. Cut out the fabric shape with scissors.
Place the paper form over a piece of double-sided adhesive paper, then trace and cut out the shape, adding 2 inches onto each edge.
Peel one side of the backing off the double-sided adhesive paper, then adhere the adhesive paper onto one side of the fabric shape. Keep the patterned side of the fabric opposite from the adhesive.
Peel off the backing from the other side of the adhesive paper, then wrap the form around the outside of the terracotta pot. Center the pot along the mid-line of the fabric form as you wrap. Overlap the excess fabric on the wrapped edge.
Snip lines along the excess fabric on the top edge of the pot, spacing the lines 1 inch apart. Fold the top cut edge over into the inside of the pot, and cut off the excess fabric along the bottom edge of the pot.
