Note that you can buy/use any fabric you like and if you have a sewing stash, this is the perfect project to use some of your stash.
One 22 Gallon plastic Storage box
One box cutter or similar tool for cutting heavy plastic
Sharpie or good marking pen
8 inch diameter object (like a bowl) or string draw a circle with pen
Optional: fabric to cover the box (I used a cotton print)
1/4 cup Tacky Glue
1 yard Fabric trim
Step 1: Cut the Lip Off
Step 2: Measure Box and Choose Fabric
Measure the length and width of your box.
Select a fabric that meets the size of your box PLUS add two inches to the length and width for overlap on the box edge.**
**Keep in mind that if your fabric has a pattern to it (a "nap") , you will probably have to position two pieces of cut fabric side-by-side to match up the pattern as you glue it to the box. This will result in needing more fabric than just what will fit. If you need assistance, pop into a local fabric store and they can assist you.
Step 3: Glue Fabric to the Box
Line up the first piece of fabric to glue to the box, leaving a 2 inch excess at the lip, or edge, for overlap onto the other side of the lip.
If your fabric has a pattern that should be right-side up (like the faces on my cat pattern), be sure that the top of the pattern points to the BOTTOM of the box. The box will be turned upside down when used as the litter box cover, so it is counter-intuitive.
Pick up a glob of glue on your finger and rub it around on the surface of the box where you will start laying the fabric. As you lay the fabric in its position- with the 2 inch overlap at the lip, coax any bubbles or creases out of the fabric for a smooth finish. Continue gluing fabric, folding corners and matching nap (pattern), as needed.
Step 4: Finish Fabric Edges
Don't worry if it looks terrible, as nobody will ever see it. But, be sure to glue securely and try not to leave gaps, as litter can get caught in the loose fabric once it goes to work.
Step 5: Cut the Entry Port
In the second picture, I am pointing to a sharpie mark that indicates the center point of where I want the entry point to be located. Mark the center point of where you want your entry port.
Find an object with a diameter of 8 inches (mixing bowl, coffee can, etc), or tie a pen to a string to use as a compass, and draw a circle of approximately 8 inches diameter around the center point mark.
Using your cutting tool, carefully cut along the circle drawn.
Step 6: Finishing Touches
If you prefer not to cover with trim, simply glue down any loose fabric on the face of the entry port, smoothing out any bubbles or creases.
Let the box dry for at least a few hours before putting it to work (see 2nd pic).
