The koozie.

Sometimes it feels like it keeps multiplying. The foam beer or soda can holder is given out at as a marketing promotion at summer festivals or in business convention bags or as a party favor at weddings, graduations, birthdays, confirmations or bar and bat mitzvahs.

When you're feeling like your koozie cup runneth over, how do you transform them into something you will actually use rather than sending them off to the landfill?

Here, we offer 12 easy ways to give new life to your koozies.

1. Pen, pencil and assorted office supply holder

This one is simple: Fill a koozie with what you need at your desk and then place it on your desk.

This also works great for kids' crayons, markers, glue sticks or scissors.

Step 2: Place it in your shower or on the bathroom sink.

3. Bike gloves

Bike handles can get hot in summer. Protect your hands by cutting up koozies and turning them into gloves.

Step 1: Cut off the bottom of the koozie with scissors.

Step 2: Where your thumb would need to poke out, use a seam ripper or scissors to cut a thumb-size hole in one of the seams.

Step 3: Place your fingers and thumb in the koozie.

You can also do these for emergency hand warmers in the winter, or you can use these koozie gloves to grab the steering wheel when your car has been baking in the summer sun all day.

4. Oven mitts

This is a great hack, especially when you are camping and don't want to bring both koozies for your cans and oven mitts.

Step 1: Place the koozie over the handle of the pot and then grab the handle where the koozie is.

Or place your hands in two koozies and grab the pot by the handle or handles.

5. Gearshift cover

When the summer heats up, avoid the burn of a hot car gearshift.

Step 1: Place a koozie over the gearshift.

Step 2: Use the koozie-covered gearshift.

Step 3: Remove the koozie after the car cools down.

6. Ornaments

Remember the festival or event by turning your koozies into ornaments.

Step 1: Cut off the bottom of a koozie with scissors.

Step 2: Cut the sides of the koozie to have two separate squares.

Step 3: On the side you want to use, with a pencil or fabric marker, trace the shape you want your ornament to be, keeping it around the center of the koozie logo.

Step 4: Cut out the shape with scissors.

Step 5: Using a needle and thick thread, poke a hole at the top of the ornament and bring the thread through.

Step 6: Tie a knot in the thread to create a loop to hang on the Christmas tree.

Alternatives: You also can use wire to poke a hole in the ornament. Then twist the wire ends together to create a loop.

If you want your ornaments to be three-dimensional:

Follow steps 1-2 above.

Step 3: Using a pencil or fabric marker, trace the same shape you want your ornament to be on both pieces of the ornament. Keep one shape around the center of the koozie logo. Draw the shape in bigger than you want it to be to allow for sewing room.

Step 4: Cut out the koozie shapes.

Step 5: Sew the shapes together inside out, leaving a space for stuffing with cotton balls. Invert the pieces to be right side out and stuff with cotton balls. Then finish sewing together the hole you used for stuffing the cotton balls.

Step 6: Follow Steps 5 and 6 above to create your hanger.

7. Placemats

These are ideal for camping or picnicking to avoid your plate touching a dirty picnic table.

Step 1: Cut off the bottoms of six koozies with scissors.

Step 2: Cut the sides of the koozies to have two separate squares for each koozie, 12 squares total.

Step 3. Arrange the squares in a four-square-wide-by-three-square-deep rectangle.

Step 4: Flip over the rectangle.

Step 5: Sew the squares together in a whip stitch, being careful to not go through the top layer of the koozies if you don't want the stitches to show. For a quick fix, use duct tape to join the koozies and skip the sewing.

Step 6: Flatten the rectangle between hardcover books if the place mat is not resting flat.

Step 7: Cut another koozie in two and use one square as a coaster for your drink.

Alternative ideas using this same technique: Use more koozies to create a play mat for kids or a kitchen mat for cooks.

8. Jewelry holder

Heading out on a trip? This one packs easily.

Step 1: Poke earrings through the koozie and attach the earring backs on the other side. For hoops, just leave them dangling.

Step 2: Put bracelets and necklaces in the center of the koozie.

9. Pincushion

Keep track of straight pins, needles and safety pins and other sewing supplies.

Step 1: Push the pins or needles through the pin cushion.

Step 2. Fill the cup with buttons, thread spools, scissors and more.

10. Save your breakables

Store breakables such as lightbulbs in the center.

Or, if you're moving, slide koozies around glasses or small vases. For larger items, cut the bottom off of some koozies to form the middle foam between two intact koozies.

You could also pack some koozies in your vacation suitcase in case you buy a breakable souvenir. Adjust the koozie shape or tape some koozies together to fit the souvenir.

11. Create a water bottle holder

Step 1: Cut off the bottom of one koozie.

Step 2: Using hot glue or duct tape or needle and thread, attach the cut koozie on top of an intact koozie.

Step 3: Use scissors to poke a hole at the top. Slide a carabiner through.

Alternative: Cut two holes on either side of the top koozie. Thread one end of a ribbon or string through each hole. Tie each end in a knot to hold. Secure with duct tape or sew the ends into the koozie.

12. Make a lunch tote or purse

Step 1: Cut off the bottoms of nine koozies with scissors.

Step 2: Cut the sides of the koozies to have two separate squares for each koozie, 18 squares total.

Step 3. Arrange the squares into two three-square-wide-by-three-square-deep rectangles.

Step 4: Flip over the rectangles.

Step 5: Sew the squares of each rectangle together in a whip stitch, being careful to not go through the top layer of the koozies if you don't want the stitches to show.

Step 6: Sew the two rectangles together on three sides, leaving a small gap an inch down at the top of the two long sides.

Step 7: In that gap, thread each end of a string or ribbon. Knot the ends. Secure with duct tape or sew the string into the koozie.
