You can make this reusable coffee cup sleeve by following a few basic steps. The idea behind a cup sleeve is to not only keep the beverage warm but also to protect your hands from the heat. Using the recommended adhesive, you can wash the sleeve and toss it into the dryer.

1

Use the ruler to measure the height of the cup. Subtract 1 3/4 inches from the measurement and make a note of the final number. This will be the height of the sleeve, which should sit at least 1 inch from the top rim of the cup and 3/4 of an inch up from the bottom edge of the cup.

2
Spread the felt onto a flat surface. Place the ruler onto the fabric and use the marker to make the measurement for the sleeve height. Cut the fabric with the scissors.

3

Wrap the fabric around the cup. Hold the fabric in place with one hand and use the marker to mark the fabric so it overlaps itself by 1/4 inch. (You’ll notice the fabric is loose on the bottom so wrap the fabric until it becomes secure at the top and bottom. It will be irregular in shape at this point but that will be taken care of later.) Mark the fabric where it overlaps at the 1/4-inch mark. Cut the fabric.

4

Wrap the cut fabric around the cup and secure the edges using the glue by spreading a thin line of glue along the inside edge of the felt where it overlaps. Press the glued pieces together while on the cup so it is secure. Let it set for a minute or two.

5

Slide the sleeve from the cup. Flatten the sleeve so the edges meet. Using the scissors trim the felt where it is uneven. The fabric can be washed after a 24-hour period.

• 1

  Look on the back of your commercial coffee sleeve to find the seam. Run a pencil along the seam to mark where the end of the cardboard is joined. Carefully undo the glue at the ends of the sleeve to open it up into one flat shape. Cut along the line that you marked at the back of the sleeve.

• 2

  Place your fabric on the table in front of you with the wrong side, or the less colorful side, facing up. Place the opened coffee sleeve right-side-up on top of the fabric, making sure that there is at least 1/2 inch of fabric showing all around from under the sleeve.

• 3

  Rubber band two regular pencils together. This will create two lines, each one exactly 1/4 inch from the other.

• 4

  Trace around the outside of the coffee sleeve with one pencil, making sure that the other pencil is making a line 1/4 inch farther away. Trace around the entire sleeve.

• 5

  Remove the coffee cup sleeve. Trace around the outer line, creating a third line that is another 1/4 inch away. You now have the outline drawn on the fabric with two more sets of lines, each one 1/4 inch farther away.

• 6

  Cut the fabric. Use the outermost line that you drew.

• 7

  Fold down the outside of this cut-out shape along the second line that you drew, which is 1/4 inch inside the cut line. Pin this folded edge down all around the fabric shape, and stitch it closed. Sew along the fold line, keeping close to the edge.

• 8

  Fold the fabric down along the third line at the top and bottom of the fabric. Pin these edges and stitch them down, sewing directly on top of the first stitching line. You now have the top and bottom of your cup sleeve hemmed.

• 9

  Fold the fabric in half with the right sides together. Fold it so that the two short ends are touching. Pin these ends together and sew them, using a 1/4 inch seam allowance. Turn the sleeve right side out and slip it onto your hot cup of coffee.

 paper cup is a cup made out of paper and often lined with plastic or wax to prevent liquid from leaking out or soaking through the paper. It may be made of recycled paper^[4] and is widely used around the world.

Printing
Paper arrives in a cup factory on large rolls. One side of the paper roll is covered with a plastic or wax backing that will eventually become the inside of the cups. These paper rolls are fed into a large machine that prints selected designs on the non-coated side of the paper. After the paper has been printed, the machine cuts apart the designs on the paper to make small sheets known as “flats.” Each flat will become a cup. Flats vary in size, depending on the size of the cups being made.

Use printed paper cups to promote your organization or create a unified look for an event. It is not possible to print paper cups at home, because a standard printer cannot print on an object like a paper cup; however, a number of online stores allow you to order and print paper cups with your organization’s logo or information about your event. Stores that sell printed paper cups usually offer two types of printing, neither of which can be performed without specialized equipment. With screen-printing, sometimes called silkscreen printing, ink passes through a stencil made from fabric. In offset printing, a plate is created for each color in an image, and the plates roll over the ink and then the item being printed. Offset printing is more expensive than screen-printing, but it offers higher quality.

Forming
After the flats have been stacked, they are fed into one end of a large machine. This machine rolls the flats into a cylinder and seals them by heating up the wax coating on the inside of the paper cups. At the same time, a roll of paper is fed into the other end of the same machine and circles are cut out of the paper to form the bottoms of the cups. The strip of paper left over after the cup bottoms have been cut is sent out for recycling. The machine brings the cup bottoms and cylinders together and heat-seals them to each other.

Rimming and Packaging
The cups are sent through a chute to another machine that rolls the paper at the top of the cups. This creates a rim on each cup. The cups are then sent through a vacuum tube to the packaging department, where they’re dropped into tubes that stack them. Once the desired number of cups is in a stack, the stack is sent through a machine that wraps plastic around it and then seals the plastic. The package of cups is then ready to be packed and shipped. The entire process of making and packaging cups takes about one minute.

Testing
Leaks are very rare. However, cups are randomly pulled off of the production line and checked. The cups that are pulled for testing are set into a special holder above a mirror. The mirror allows the person performing the test to see the bottoms of the cups and make sure they’re not leaking. If a leak is found, production on a particular line is stopped until the problem can be found and corrected.
