WHAT YOU NEED:
- Turquoise T-Shirt
- Light Gray and White Craft Foam
- White and Yellow Felt
- White Headband
- Hot Glue Gun
- Polyester Fiberfill Stuffing
STEP 1: CUT OUT EARS FROM CRAFT FOAM
The first step is to cut out the small triangle shaped ears and larger ears from the craft foam.
For the smaller triangle ears, use the white foam. Cut out a triangle the size you want to make the ear. Use the first triangle to cut the second one by tracing around it and then cutting out the foam. This will ensure the two ears are the same size and shape.
With the light grey craft foam, cut out two inner ears in the same manner. Cut one and then use it to trace and cut the second one.
Next, from the white craft foam, cut out the larger ears. These are more oblong in shape. Use the first one as a template, tracing around it onto the craft foam and then cut the second ear.
STEP 2: GLUE THE SMALL EARS
Using the hot glue gun, glue the light grey inner ears onto the white triangle shaped ears. Then, glue the ears onto the top of the headband. Make them slightly curved so they show some dimension.
Kids should always have adult supervision when using a hot glue gun.
STEP 3: GLUE THE LARGE EARS
Place the large ears next to the headband. Trim the side of the ear to curve like the headband.
Using the hot glue gun, glue the larger ear to the sides of the headband.
The Temmie ears headband is complete.
Next, we show how to make the Undertale Temmie Shirt.
STEP 4: TEMMIE SHIRT CUT STRIPES
Cut strips from the yellow felt that are 2" wide. They need to be long enough to go across the front of the shirt from seam to seam.
We used three strips across the shirt. If your shirt is longer, you may want to place more yellow stripes.
Stripes can also be placed on the sleeves. We decided to not put stripes on the sleeves for our costume. Stripes on the sleeves would need to be glued on since it would be very difficult to sew them with a machine. If you are hand sewing the stripes on, it may be more manageable to sew.
STEP 5: SEW OR GLUE ON STRIPES
If you will be wearing the Temmie shirt only for Halloween, you could probably get away with just gluing the stripes onto the shirt with fabric glue.
To make a more permanent shirt that can be washed and dried, sew the stripes onto the shirt. Pin the stripes to the front of the shirt and using a zig-zag stitch, sew all the way around each stripe.
The stripes could also be hand-sewn onto the shirt.
STEP 6: MAKE TAIL
Make a template for a tail. Cut the template out of the paper. Pin the template to two layers of white felt. Cut out the tail.
Sew around the tail with a 1/4" seam allowance. Leave the end of the tail open where it will attach to the costume. Clip the curves on the tail and then turn it with the right side out. Push out the curve.
Stuff the tail with some polyester fiberfill stuffing. Sew the end of the tail closed.
Pin the tail to the back of the shirt if it's longer. The tail could also be pinned inside the shirt and hang out. If the shirt is shorter, pin the tail onto the back of the pants.
Here are photos of the finished costume.
Add a pair of grey pants and the costume is complete. Here is the tail pinned to the back of the shirt.
