It is easy to make a sheep costume. Plus, it can be tailored to fit both a child and an adult. All you have to do is wear clothes of different sizes. To do this, get a black or white sports outfit and cotton balls or polyester fill. Use hot glue or craft glue to glue the cotton balls or polyester to your clothing. Decorate your head with ears and tufts of wool using a headband, a hat or the hood of your sweatshirt. Finish off the costume with a black nose, hoof stockings, and black ribbon around the wrists and ankles.
Steps
Part 1 of 3: Create the Body of the Costume

Step 1. Choose a sports outfit
Choose a sweatshirt and sweat pants that are the appropriate size for the person who will be wearing the costume. You can choose a white outfit for a completely white sheep or a black outfit for a black sheep. Choose a hoodie for a version of the costume or a crewneck if you want the hat or headband to be separate.
- If you think you will feel too hot in a sports outfit, you can wear a long-sleeved shirt. Sweatpants are probably the best option for your costume, unless you want to choose leggings, leggings, or other plain black or white pants.
- If you are wearing clothes that you already have instead of buying new clothes for the costume, remember that you are going to use permanent glue. Once you make the costume, the clothes will be ruined for regular wear.

Step 2. Choose cotton or polyester balls
To make a costume for a toddler, you can use cotton balls since you won't be covering a large area. If the costume is for an adult, it is best to use a type of synthetic cotton or polyester fill as it will stick more quickly and cover more area than cotton balls. You can also use polyester for a child's costume.
- You can buy cotton balls at any store or pharmacy. You can buy the filling at large supermarkets, but you may have to go to a craft store.
- The cotton balls will give your costume a more textured and authentic look, but the polyester filling will stick much faster and cover more space. If you're in a rush, don't use cotton balls.

Step 3. Wash the clothes
It won't be easy to wash the costume once it's fully assembled, so wash everything first if you'd like. It is good to wash new clothes especially to soften them a bit and make them more comfortable. It is not necessary to wash clothes that you have already worn several times before if they are clean.

Step 4. Glue the polyester padding or cotton balls to the clothing
Use hot glue or fabric glue to begin gluing the cotton to your shirt and pants. Gather the polyester fill as you glue it together to make it look like sheep's wool. Place the cotton balls together so there are no gaps.
You don't have to cover the entire surface of the clothing with cotton. You can leave a few inches free at the end of the sleeves and pants to mimic the way the sheep's wool stops before reaching the hooves
Part 2 of 3: Making Your Sheep's Head

Step 1. Depending on your costume, cut black or white felt into the shape of the ears
Make them about 6 inches (15 cm) long and 2 ½ inches (6 cm) wide. Use a layer of felt for basic ears, or sew two pieces of felt for fluffier ones. Both pieces can be the same color, or you can create an inner and outer ear using a black and white felt piece for each ear.
- Get creative to make the ears look the way you want. Stuff the felt pieces with a few cotton balls or some polyester filler before sewing to make them look plump.
- Use black and white paper or another fabric if you don't have felt or don't want to buy it. Use just one piece of felt for each ear if you don't want them to be double thick.

Step 2. Glue the ears to a plastic headband
Glue the ears to the headband so that they slant down or stick out to the sides. Cut out a circle of white paper and glue several cotton balls on top. When finished, glue it to the top of the headband to mimic the tufts of wool on top of the sheep's head.

Step 3. Wear a black or white cap
Wear a white or black wool cap, and sew or glue the ears to the sides. Take a couple of handfuls of cotton balls and glue them to the top of the hat. Make sure to wear one that fits you perfectly and does not have a pom pom on top or is not dropped in the back.
If you don't want to glue the ears to the cap, put the ear headband over it

Step 4. Wear the hood of your sweatshirt as your sheep's head
If you bought a hoodie, you can glue the ears and wool strands from the head directly onto the hood. Sew or glue the ears to the sides of the hood, and glue some cotton balls to the top. This option will allow you to easily remove the head part if you start to feel too hot inside the costume.
Part 3 of 3: Add the Final Details

Step 1. Wear black stockings on feet and hands
One way to make your costume look even more realistic is by wearing long black stockings to make them look like hooves. If you will be wearing it outside, wear black shoes. If you want, you can take them off when you are at home. You can also wear black gloves or mittens so you can use your hands.

Step 2. Paint the tip of your nose black
Use washable craft paint, black lipstick, or black eyeliner to paint the tip of your nose. Avoid painting up to the bridge of your nose or below your nostrils. Paint a section about 1 inch (2.5 cm) in diameter at the tip of your nose.
Paint six or seven dots above your upper lip, below your nose, to simulate whiskers. Also, wear red lipstick to highlight your makeup

Step 3. Wrap your wrists and ankles with black tape
If you choose a white sweatshirt and are not wearing socks or gloves on your hands, use black tape on the wrists and ankles of the clothing to mimic where the wool ends and the hooves begin. Duct tape or sports cloth tape will work well.
