Cutting & Pattern Prep

  • Print pattern pages and tape them together into a grid as instructed on the PDF file. To assemble the grid, cut one short side and one long side off of each page to make it easier to tape together. Cut out pattern pieces.
  • Fold the fabric in half to quickly cut out the pieces 2 at a time. Lay all the pieces out on the fabric for placement before cutting.
  • Pay attention to the “stretch” lines on the fabric and place those lines parallel to the direction the fabric stretches the most.
  • Use pattern weights to hold the patterns in place while cutting. Table knives from your kitchen work great in a pinch.
  • After cutting, transfer Ear placement markings onto 2 of the Hood Side Panels and transfer the Mane placement markings onto the Outer Hood Center Panels.
From the white knit fabric cut:

4 pieces using the Hood Side Panel pattern (2 Right Side Hoods, 2 Left Side Hoods)
1 piece using the Hood Lining Center Panel pattern
2 pieces using the Outer Hood Center Panel pattern (1 Right Side panel, 1 Left Side panel)
4 pieces using the Ear pattern

From the Gold Lame fabric cut:

1 piece using the Horn pattern
4 pieces using the Wrist Hoof pattern
4 pieces using the Ankle Hoof pattern

From the medium weight fusible interfacing cut:

2 pieces using the Ear pattern
4 pieces using the Wrist Hoof pattern
4 pieces using the Ankle Hoof pattern

From the Tulle cut:

3 stacks (16 layers thick) of 3’’ x 5’’ strips from each color for the Mane (12 stacks total).
4 stacks (16 layers thick) of 3’’ x 12’’ strips from each color for the Skirt (16 stacks total).

*Tip: Cutting the tulle into 16 layer stacks is easiest done by folding the tulle into 8 layers, cutting two 7 inch strips (14’’ for the Skirt stacks), and stacking them on top of each other. Then use a rotary cutter and mat to square off the edges and cut the strips. tulle tends to get unruly quickly. Keep it stacked up nicely by clipping the layers together with binding clips on one end. Trim a corner off of each stack to create a curved end on each strip. Note: If the tulle is wrinkled iron it before cutting for best results. Keep your Iron setting low to start with so you don’t melt the tulle.

Sewing Instructions

*All seams are sewn with a 1/2‘’ seam allowance unless otherwise specified.

Make the Hood Lining

With right sides together pin a Right Hood Side Panel to the Hood Lining Center Panel. Sew the panels together.

Unicorn

With right sides together, pin a Left Hood Side Panel to the other side of the Hood Lining Center Panel. Sew them together. Press the seams open as much as possible with a warm iron. Set this Hood Lining aside.

Unicorn

Make the Ears

Fuse the Medium weight interfacing to the wrong side of two Ear pieces. With right sides together sew a interfaced Ear piece to a plain Ear piece along the curved edges of the triangle with a 1/4’’ seam. Clip and notch the curves and point. Turn right side out and press. Repeat for the 2nd Ear.

Unicorn

Fold each ear in half at the base and tuck the fold in to make a little pleat so that the Ear stands open a little easier.

Unicorn

Baste the Ears onto the right side of a Right and a Left Hood Side Panel between the Ear placement marks. Make sure the Ears are facing forward. Set aside.

Unicorn

Make the Mane

Set the machine to sew a gathering stitch (5-6mm stitch length). Sew a row of gathering stitches about 3/8’’ away from the short, straight end of a stack of 3’’ x 5’’ strips. Alternating colors, place the next stack right next to the other and continue to sew along the top connecting the stacks together. Alternate stacks in a rainbow pattern and make sure the curved ends are going the same direction. Sew a 2nd row of gathering stitches 5/8’’ from the edge.

Unicorn

Pull the top 2 threads evenly from each side and gather the Mane so that each 3’’ strip shrinks down to 1’’.

Unicorn

Set the machine back to a regular stitch length (3 mm). With the right side of the fabric facing the Mane, pin the Mane to the straight side of an Outer Hood Center Panel between the Mane placement markings. Make sure the curved ends point toward the Neckline. Sew between the 2 rows of gathering stitches with a 1/2’’seam.

Unicorn

Pin the 2nd Outer Hood Panel to the the mane with right sides together and stitch in place along the same 1/2’’seam line.

Unicorn

Finish the Hood

Sew the Outer Hood together in the same fashion as the Hood Lining. (See steps 1-2). Check every few inches to make sure the layers of the knit lay flat as you sew. It is easy to for them to bunch up underneath if you are not careful. Press all seams open as best as you can.

Unicorn

Sew a row of stay stitches in the seam allowance at the base of each Ear with the seam allowance folded toward the Hood Side Panel. This will help the ears to stand up.

Unicorn

With right sides together, match the seams of the Hood Lining and the Outer Hood and pin them together around the face opening and all along the neckline. Making sure the Mane doesn’t get caught in the seam, sew around all the edges leaving a 4’’ opening in the bottom of the neckline for turning.

Unicorn

Trim the corners and clip into the seam allowance of the curves.

Unicorn

Turn the Hood right side out through the opening and press around the edges so the Hood Lining sits nicely inside the Outer Hood. Pin the opening closed. Sew all the way around the Hood about 1/8’’ away from the edge. Attach the Hook and Loop tape to the front flaps by stitching around it close to the edge. It is helpful to sew around the tape twice if the Hood is going to be used a lot for dress up. Also, remove any gathering stitches that are showing on the Mane.

Unicorn

Make the Horn

Sew a row of stitches 1/2’’ away from the curved base of the Horn. This marks the line where the Horn will meet the Hood. Sew a row of gathering stitches about 1/4’’ away from the same edge.

Unicorn

Fold the horn in half with right sides together and stitch along the side with a ½’’ seam allowance. Clip the corner at the point.

Unicorn

Turn the Horn right side out and stuff it. Use small bits at first to help fill up the point. Stuff it just enough for the Horn to be firm but not distorted. Pull a gathering thread to cinch the end a little until the fabric folds along the 1/2’’ stitch line.

Unicorn

Pin the Horn just in front of the Mane, overlapping the Mane about 1/4’’ Hand stitch the Horn through both layers of the hood coming up with the needle just to the outside of the stitching line on the Horn so it disappears as you sew.

Unicorn

Make the Skirt

Cut a piece of 1’’ elastic to the length of your child’s waist. Using the longer stacked strips of Tulle fold the straight end over the elastic about 1 1/2’’. Stitch along the edge creating a casing for the elastic. Do not sew on the elastic. Continue to add the strip stacks in a rainbow pattern. Pin the end of the elastic to the first tulle strip so it doesn’t slide out. While keeping the needle down on the machine slide the elastic through the casing to gather the strips of tulle making room for the rest of the strips to be sewn onto the elastic.

Unicorn

When all the strips are sewn together, pull out the ends of the elastic and overlap them about 1/2’’. Stitch the elastic together in a few places using a zig zag stitch. Backstitch a few times to secure. Smooth the gathers out evenly and your skirt is done.

Unicorn

Make the Hooves

Fuse a piece of stabilizer to the wrong side of each Hoof piece. With right sides together sew around the Hoof using a 1/4’’ seam allowance. Leave an opening for turning along a straight side. Clip the corners and the curves.

Unicorn

Turn the Hoof right side out and stitch a strip of hook and loop tape to each straight side. Repeat for each of the Hooves. You should have 2 small ones for the wrists and 2 larger ones for the ankles.

Unicorn

I think the Hooves make a fun little detail to finish off the costume don’t you?
