D.I.Y. giant outdoor noughts and crosses
On a length of pine, use a combination square to mark 280mm from the end, cutting with a mitre saw to make a tile template for marking out and cutting 28 tiles from the remaining pine. Keep the offcuts. Smooth the cuts and round over the edges of the tiles with 180-grit abrasive paper.
Make a square stamp from an offcut, using a combination square to mark 140mm from the end, cutting with a mitre saw. To draw a grid, adjust the combination square to 70mm, marking lines horizontally and vertically. Adjust it to 35mm to mark around the edges.
Remove the backing from six felt pads, positioning them on the grid to make a six-spot pattern. Use scissors to cut a 67mm floor protection strip in half lengthways, remove the backing and centre it along the base of the stamp, flush against the edge.
Wearing gloves, pour paint onto a plastic plate. Hold the stamp, felt-side down, in the paint to saturate the felt pads and strip. Hold the stamp over the lower half of a tile and press to transfer the pattern. Repeat to make the appropriate number of ‘six' tiles, reloading with paint every three tiles. To make the double-six tile, flip the stamp, line up the middle felt strip and press.
On the stamp, remove the two middle spots and position a new one in the centre, creating a five-spot pattern. Remove or add felt pads on the grid to create the remaining spot patterns and repeat.
Tip: The felt pads can become saturated with paint and come unstuck, so check them before reloading with paint and replace as necessary.
To make the double-zero tile, take a full floor-protection strip, remove the backing and adhere it to a 25mm dowel offcut. Saturate with paint and centre it over the remaining blank tile. Touch up uneven spots on the tiles by adhering a clean felt pad to the dowel and reapplying paint as needed.
