Waterproof crate cushion

Step 3 Trim the shower curtain

Spread the shower curtain out on the floor, design side down.

Place the egg crate peices on top of one another with the bumpy side down. If there's a specific part of the shower curtains design that you want shown, place the egg crate on top of that.

Then wrap the curtain around the egg crate and trim off the excess shower curtain, making sure to leave a little on each side for overlap. Also make sure that you trim off the area with the metal rings.
