How to Make a Unicorn Costume

1. To make the mane, use the Titanium Softgrip® Comfort Loop Rotary Cutter to cut several strips of felt about 9" long and 2" wide.

2. Fold each felt strip by overlapping the short ends slightly at the center.

3. Pin each folded felt strip to the hoodie, starting about 4" from the edge of the hood and continuing down the back of the hoodie.

4. Using a zig-zag stitch, sew through the center of the felt strips to join them to the hoodie.

5. Use the Amplify® Fabric Shears to snip into the felt strips to create volume.

6. Make two ears by cutting triangles from the felt, layering a larger triangle behind a smaller triangle. Sew the two triangles together through the folded center, to create a seam. This will help the ears to stand up instead of lying flat.

7. Pin the ears to the top of the hood, one on each side of the mane. Hand stitch the ears to the hood.

8. To make a horn, cut one large felt triangle using the Amplify® Fabric Shears. Stitch the two long edges of the triangle together to close it into a cone shape. Stuff the horn with fiberfill as you go.

9. Stitch the base of the horn to the front of the hood.

All that is left is to grab a bucket and it is time to trick or treat!
