Tutorial: DIY Unicorn Legs

How to sew Unicorn legs for Halloween or dress up.

It’s the beginning(ish) of October which makes it costume time around here. Here is the good news, if you are finding this tutorial on the morning of the 31st you’ve still got plenty of time. This is a super fast sew.

My girls have decided to be unicorns this year. Well, my oldest girl decided to be a unicorn and her younger sister thinks the moon revolves around her so now I’ve got two unicorns.

The last few years I’ve been buying some/all of my kids’ costumes and honestly not feeling guilty about it. But this falls under things I can make that either will use scraps I have or be able to be worn again.

Mix up your fur or feather options and these legs can be used for whatever animal your kiddo wants to be.

YOU NEED:

Your kid’s leg measurement. I fit mine just over the knee to ankle. However, for big sister, they’re going to hit below her knee, do what makes sense for your kid.

Measure around the widest part you want it to fit and take a length measurement from that point to their ankle/top of the foot.

Fur remnant based on their measurements (read on to figure this out)

Scraps of a knit with good recovery

1/2″ or 3/8″ elastic about 24″

HOW TO CALCULATE YOUR PIECES: 

My kid’s leg is about 10″ around above her knee. I’m going to add 2″ to make room for seam allowance, her foot going through, and general comfort.

Above her knee to the top of her foot is about 10″ also.

The size of my fur rectangle will be 12 inches wide by 10 inches tall. I need two. So your formula for fur rectangles is the widest part of the leg + 2 inches by desired height. Pay attention to the direction your fur lies when you cut.

Your knit band and elastic are going to hold up the top of your leg. They will both be cut 80% of the width of your leg measurement. So my kid’s leg was 10″ around, I cut the elastic and knit band 8″ long. Your knit band will be 2″ tall.

So my knit band is 8″ wide (the direction of the stretch) by 2″ tall. Your band with by 80% of your leg measurement wide by 2″ tall.

Ok have you got your sizing? Congrats! That is the hardest part. Let’s sew.

SEWING

First, you’ll need to cut out your fur rectangles (based on the math you just did). Remember to make sure your fur is going the correct direction.

Pin them right sides together. You’re going to be sewing up the side of leg seam, your height or length measurement.

Make sure as you pin you’re pushing the fur into the sandwich. This will reduce the amount of fur that gets sew into the seam.

All that fur sandwiched inside, now sew down the edge at 3/8″ seam allowance.

Flip it right side out! Because I pushed all that fur out of the seam before I sewed it’s already almost invisible. If you have a bunch of fur clearly sewn into your seam gently pull it out with a seam ripper or awl. Just lightly tug and then fluff it up.

Repeat for your second leg.

Set aside your fur for a minute. Overlap the ends of your elastic and zig zag over it a whole bunch of times. You’ll have two untwisted loops.

Take your knit band and fold it right sides together. Sew the short end. Do this with both bands.

Fold your band in half, wrong sides together. Sandwich your ring of elastic inside. Now if you are using nice band material you may not realllllyyyyy need the elastic. Since they are going to be wearing this trick or treating- and I’m not taking any chances with the toddler- I opted to add the elastic.

Take your entire sandwiched band and match the raw edges to the top raw edge of your fur piece. Keep in mind your band is much smaller than your leg. That’s why your band needs to be really stretchy with good recovery.  Depending on the stretch of your knit you may need to make your pieces wider than 80%. But remember that is what is holding your leg up so be careful not to make it too big that it doesn’t hug the leg.

Sew across the raw edges at 1/4″ gently stretching the band as you go. This step is a pain.

Flip up your band. The folded edge will now be the top of your leg and the seam will be safely inside. I chose to leave the bottom edge as is. If you wanted a more contained look (or a better way to stop the shedding of fur) you could put a second band along the bottom.

Go forth and make unicorn legs!

Worth noting we are in a weird bit of ridiculously warm weather. I’m planning on these going over a pair of leggings on Halloween. If you are planning for something bulkier (Hey I’m from MN I get it) make sure you measure over the clothing item.

If you are looking for more inspiration you could pair it over this cool unicorn leotard or pair it with a headband horn.
