A fox tail costume is a fun and simple way to add a touch of whimsy to any outfit. You can use the tail as a very basic costume for fancy dress parties or you can also wear the tail with a regular outfit to give yourself an animalistic look. The key to making a tail -- usually known as a "brush" when attached to a fox -- is finding the best fur for the job. If your fur is too thick, it will not sew together well on the sewing machine. A thin fur is best for making tails.
Draw the outline for the tail on to a piece of paper, or you can print a pattern for the tail. Make the top of the pattern 10 cm (4 inches) across, narrowing to 7.5 cm (3 inches) about 20 cm (8 inches) down. From there, widen the tail to 25 cm (10 inches) across and gradually taper down to 20 cm (8 inches) wide about 30 cm (12 inches) down. The tip of the tail should be rounded, and 10 cm (4 inches) tall and 15 cm (6 inches) wide.
Cut out the tail pattern on to a piece of scrap fabric. Sew this tail together and check for fit and shape. Adjust the pattern as necessary to create the tail shape that you want. Draw the new pattern on to a new piece of paper if you make any adjustments.
Transfer the pattern design on to the back of the fur using a marker or chalk. Use a pet brush to brush the fur away from the cutting line, so that the fur will hang over the seam rather than getting cut off along the cutting line. Cut out the pattern.
Turn the fabric wrong side out and sew together along all seams. Leave the top seam open so you can stuff the tail.
Turn the tail right side out and stuff with stuffing. Hand sew the bottom tail piece to the longer tail piece. Hand sew the top opening closed where you placed the stuffing. Leave a loop on both sides of the hole so that you can slide a belt through. You can also add a small elastic loop to slip over a belt. Brush the fur over the seams to hide the sewing line.
