If you’ve got the open space in a large backyard, freezing cold temperatures, and a love for ice skating, you could make you own ice rink. Imgur user legojerry created his own with lumber and polyethylene plastic.

Using 2×4s for the perimeter, he first laid them all out to create his outline. He used 50 1″×2″×18″ stakes for stability, and 1×4s on all of the seams for added strength, inserting the screws from the inside and screwing them in flush so that they wouldn’t interfere with the liner. To correct the 5½ inch incline of his yard, he added 7/16″ oriented strand board to add height, since water self levels and since it was such a large level difference. After it is all inserted and screwed in, you can add the plastic liner. He used 6 mil 20’×45′ polyethylene plastic, but adds that a bigger liner would ensure at least a foot of excess on each side of the boards.
