Maybe your kids have a school play coming up, or perhaps a fancy dress party is around the corner. Maybe you just like dressing like Australian wildlife. For whatever reason, someone in your family has announced that they need a kangaroo costume. You could spend days driving around town looking for one, or you could just make your own. Making your own kangaroo costume will save you money and it allows you to create your costume in any colour you like.
Select your sweatshirt and matching tracksuit bottoms. These will form the basic body of your costume.
Make the tail, using the craft felt. Cut a long, narrow triangle, about 75 cm (30 inches) wide at the base. Make the triangle about 90 cm (3 feet) long at the centre apex. Fold the triangle in half lengthwise, turn inside out, and stitch along the long edge. Leave the short bottom edge open. Turn the tail so that it is now right side out, and loosely stuff with fiberfill. Pin the short edge closed.
Sew the short edge of the tail to the seat of the tracksuit bottoms, making sure you catch both sides of the tail fabric in the stitching to close it. You can position it anywhere you like, but ideally you should align it with the rear centre seam of the trousers. Before sewing it on permanently, pin it in place and try on the trousers to make sure the tail doesn't hang too low. Adjust as needed.
Cut a piece of the craft felt about 30 cm (12 inches) wide by 17.5 cm (7 inches) high, rounding off the bottom two corners to form a U-shape. This will be the kangaroo pocket. Place it so that it is centrally positioned on the front of the sweatshirt, and sew it in place around the side and bottom edges. Leave the top open, and if you like, carry a toy baby kangaroo in the pocket.
Cut a pair of ears from the felt. Make the ears about 7.5 cm (3 inches) across at the base, and taper upward into a point about 12.5 cm (5 inches) long. Fold each ear in half at the bottom edge, and sew onto the hood of the sweatshirt. Put on your kangaroo costume, and start bouncing around!
If you're making this costume for a child who won't keep a hood on, consider attaching the ears to a ball cap or knit cap instead.
If you will be walking a lot in this costume, check to make sure your tail doesn't drag along the ground -- you don't want to trip over it in the dark.
