Bring your child's imagination to life with this dinosaur hat and tail that will have them roaring in no time! This costume is great for Halloween, birthday parties or just every day dress up.
Measure the circumference of your child’s head (Image 1). For tail length, measure from the middle of your child’s head, down their back to where you want the dinosaur tail to end (Image 2).
With the stretch going from left to right, cut four hat shaped pattern pieces (half ovals). The bottom straight edge should be the same width as your child’s head circumference divided by two. The top center of your hat should be approximately 10" in length from top to the bottom, arcing down on both sides (Image 1).
Make sure that the stretch in the knit fabric is going from left to right, not up and down. To figure this out, simply pull on your fabric gently to see which way it stretches (Image 2).
To make the spikes for your dinosaur tail, cut a strip of felt the same length as your tail length by 10" wide. Fold the strip in half lengthwise so it is 5" wide. Cut out various triangle shapes along the top of the felt strip, making sure to keep it attached at the bottom. Cut two or three of these felt strips, depending on how many spikes you want sticking out (Image 1). Then, cut out a few of triangles from the felt to turn into spikes just for the hat (Image 2).
For additional dinosaur decoration, cut felt circles in various sizes (Image 1). Place the felt circles on top of the two tail fabric pieces and pin. Adhere the circles with fabric glue or sew a curved line around each circle (Image 2). Then, attach the circles to the two hat pieces (Image 3).
Place another hat pattern piece right sides together with the triangle felt hat piece, sandwiching the spikes in the middle. Pin around the outer curved edge and sew (Image 1). Turn the hat right side out (Image 2). Repeat for the other two hat pattern pieces, placing right sides together and sewing the outer curved edge. (The second set will be the lining of the hat.) Set aside all the hat pieces for now.
Place the other decorated tail pattern piece on top of the felt spike tail pattern, right sides together, sandwiching the spikes in the middle. Pin along the long straight edge and sew to secure (Image 1). Unfold and you should now have this (Image 2). Place the other two tail pattern pieces right sides together and sew along the long straight edge. These will be the underside of the tail.
Place the two tail pieces right sides together, sandwiching the spikes once again in the middle. Pin all around the sides and bottom, leaving the top open (Image 1). Sew around. Turn the tail right side out through the top open edge and press (Image 2).
Place the hat lining inside of the decorated hat, right sides together matching up the side seams. Pin around the bottom straight edge, leaving a 4-inch opening for turning (Image 1). Sew around, using a stretch stitch, serger, or zigzag stitch when sewing. This will ensure that your hat will still have the stretch it needs to go on and off your child’s head. Turn hat right side out through the 4-inch opening (Image 2).
Image 3 shows a close up of a stretch stitch. Most sewing machines have a selection of stitches that allow stretch, check the manual. If unsure, a basic zigzag stitch will always work. Essentially a stretch stitch allows the threads to be spread apart and pulled, unlike a basic straight stitch.
Slip the top edge of the tail inside the 4-inch opening and pin it closed (Image 1). Sew around the bottom edge of the hat once again to secure. Again, use a stretch stitch. Lay out your dinosaur hat, and you're finished! (Image 2)
