Cover the base of a 200g tin with fabric by first measuring the can’s circumference and depth, then cut a rectangle to these dimensions with an extra 5mm added to the circumference. Snip a strip of contrasting fabric to the circumference measurement, 5cm wide. Stitch this to one of the long edges of the rectangle with a 1.5cm seam allowance.

Wrap the strip around onto the wrong side and stick it in place with fabric glue. Repeat on one of the short ends of the rectangle, cutting the strip 1cm longer to enable the raw end of the strip to fold over to the wrong side of the bound edge. Now the rectangle can be stuck with double-sided tape or glue to the tin can with the bound edge at the base.

Cut two rectangles, one in each of the fabrics, to the circumference plus 2cm and a height of 15cm. Fold one of the rectangles in half with the two shorter ends matching, then find and mark the centre point on one of the long edges. Open out the rectangle and make a notch 5mm away on both sides of the centre mark.

Position the zip end with the stoppers to one of the shorter ends of the rectangle and the length of the zip running along the long edge, with the right sides of the zip and the fabric facing one another. Open the zip, pin and stitch in place as far as the 5mm notch. Repeat the process, stitching from the opposite side as far as the opposite 5mm notch. This should create a gap in the stitching line of 1cm and the remaining length of the zip hanging in the centre of the piece.
