How to Make a Skirt Pattern – Draft a Skirt Sloper or Block

Hey y’all, today I’m going to show you how to make a skirt pattern. If you’ve been a reader of this site for a long time, this is an update to a an old post that now contains VIDEO – yes! If you’ve never seen this post before, welcome. I hope you learn a lot about skirts and flat patterns from this.

So, we’re going to be drafting our own patterns based on our measurements! That’s right – starting from scratch.

Never fear, skirts are the easiest thing to start patternmaking with. But never fear, skirts are the easiest thing to start patternmaking with. So grab your drafting tools – kraft paper or wrapping paper (use the back side), a pencil and a ruler, preferably a clear one (here’s an affiliate link to the one I use in the video) You’ll also need some muslin (or fabric from your stash),  we’re going to be drafting and fitting a basic fitted skirt. Then I’ll show you how to take that basic skirt pattern and turn it into all of these skirts:

So hike up your skirts (sorry, couldn’t resist) and get ready to draft and sew!

To start with, you need four measurements: your waist, your hips, your waist to hip length and your skirt length (for this we’ll be using a waist to knee measurement). Let’s discuss more.

Waist: This can be your actual waist, or where you want your skirt to sit.I prefer to do actual waist and then change up my pattern from there.

Waist-to-Hip: You may want to put a sticker on yourself level with the tape while holding the measuring tape for the waist and hip measurements, so that you can easily measure the distance between your waist and hip. Alternately, you can tie yarn around yourself at both levels and measure that way. This is a vertical measurement.

For more help with correct measurements, you can check out the video in this post. 

If you’d like a handy measurement card to record these and other measurements, you can click on the image below to get a PDF. Just make sure to add the Waist-to-Hip and Waist-to-Knee measurements to it for yourself.

In the video below, I show how to draft the basic block. You can also watch that on YouTube here. Or if you prefer written instructions, check below the video.

OK, we’re ready to draft. Get out some kraft paper, use the back side of a roll of wrapping paper (the kind with grid lines is especially handy) or tape a bunch of printer paper together.  Grab your ruler. Also make sure you have a pencil, and some muslin (or scrap fabric – enough to cut out your skirt) and pins. When it comes time to fit the muslin, you’re also going to need a friend or a spouse, and a fabric marker or chalk.

We’re going to draw 1/4 of the skirt for the pattern, so you’ll need to do a tiny bit of math. Calculator (or more likely, phone) at the ready! Start by dividing your hip measurement by 4. Add 1/2 inch to that number, then draw a rectangle that is that wide and your desired length (suggested: waist to knee measurement) tall.

But wait Melissa, I’m not a rectangle! Of course you’re not. This is just our starting place. Now we’ll work on the waist.

A bendy ruler works well to draw this curve, as does a French curve. Or a dinner plate. Just make sure the majority of the curve is in the top 3″ or so, because that’s where the body curves the most.

Add seam allowances to the  side and waist, then retrace the pattern and add the center back seam allowance, and you have your muslin patterns.  Cut out the front piece on the fold, and two back pieces mirrored. IMPORTANT: you’re going to want to mark the hip line on the muslins.

Pin up your center back seam, and one side seam. Then put the skirt on yourself, inside out. Pin up the remaining side seam. You may need assistance from your spouse or friend (frouse? spiend?).

Starting in the front, smooth your hands together from the center and side seam to pin the front darts. Pin the excess fabric at the waist. Repeat on the other side. This isn’t too hard to do yourself.

But then you’re going to need your spouse/friend/spiend/frouse  or whatever to help you in the back. Because trying to pin back darts on yourself results in getting stuck with pins. And other bad stuff. So as you did on the front, have your friend smooth the fabric in the back and pin the darts in the waist.

If the muslin is tight around your rear, let out the pins in center back seam first, not the side seams.

Next we need to determine where those darts will be positioned. It’s easier to start in back with this, and it involves some looking at your rear (Omigod Becky, look at her…just try not singing “I Like Big Butts” while you do this). With the fabric marker or chalk, you’ll want your friend to mark the point where your buttocks start to curve toward your back (mark 1) and where they start to curve out toward the hip (mark 2).

In the front, you’ll need to do the same thing, except the curve will be your tummy instead of your butt. Of if you’re a flat ab workout queen, you may not need front darts. And many women might secretly hate you. Kidding. Sort of.

Now, check out your side seams. Make sure they’re going straight down your sides. If they’re not, unpin and adjust until they are.

Now use your marker or chalk to mark where the pins are on the side seams and back seam.  Then unpin yourself  down one side and take off your muslin. Excuse your friend/spouse and thank them for their help, you’re on your own from here on out.

Mark the pins that are holding the darts, on each side of the dart. Then you can remove those pins.

We’re going to figure out where the darts go. Measure over on your lines that marked the curve breaks on your body; where they intersect is the bottom of your dart. Transfer these measurements to your paper pattern, and mark the bottom of the dart. Repeat with the front dart on the front pattern piece.

Now measure the width of your darts on your muslin.

Make a straight line up through your dart point, perpendicular to the hip line on your pattern.

Repeat this dart creation for the front piece. Finally mark off your side seams and adjust the seam allowances. You now have a skirt pattern!

Now, it’s a good idea to make another muslin and test this pattern before you cut into the good fabric, but any adjustments should be minor.

Ok, time to show you how to take the pattern we drafted and turn it into other variations.

Let’s start with adding facings – the facings and sewing a zipper into the center back seam are the only things I added to make this fitted skirt.

You’ll cut your facings on the fold, just like your skirt. Since your skirt already has seam allowances, so will your facings – no need to add them.
Steps to sew this skirt:

1. Sew back darts
2. Sew back center seam and put in on seam zipper (see this tutorial)
3. Sew front darts
4. Sew side seams on both skirt and facings
5. Sew facings on to skirt (pin facing to waistline, right sides of fabric together, stitch around, then turn facing to inside of skirt and press. Topstitch if desired)
6. Hem

This A-Line skirt I made is fully lined, so no facings. This is a super simple skirt variation.

Steps to sew this skirt:

1. Sew back darts
2. Sew back center seam and put in on seam zipper (see this tutorial)
3. Sew front darts
4. Sew side seams on skirt
5. Repeat steps 1-4 with lining
6. Sew lining to skirt (pin lining to waistline, right sides of fabric together, stitch around, then turn lining to inside of skirt and press. Topstitch if desired)
7. Hem both lining and skirt

If you think about how you make facings and how you make an A-Line skirt, the next variation is really easy to grasp too.

For the A-Line above I also off-centered some ribbon trim, and I finished the waist with the same ribbon. Steps to sew this skirt:

1. Sew decoration onto front.
2. Sew back center seam and put in on seam zipper (see this tutorial)
3. Sew side seams
4. Bind waistband with bias tape or grosgrain ribbon (see this tutorial)
5. Hem

What if you want to add a yoke?

First you’ll create an A-line shape with no darts, then you’ll just cut the pattern where you want the yoke to be,  and add seam allowances.

Steps to sew this skirt:

1. Sew yoke together at side seams.
2. Sew skirt side seams
3. Sew back center seam and put in on seam zipper (see this tutorial)
4. Sew facing or lining to waistband, turn to inside
5. Hem

And finally, how to add a flounce. Remember when doing this type of skirt that you may want to remove length equal to the vertical length of your flounce so that the entire skirt length stays the same.

Steps to sew this skirt:

1. Sew side seams of flounce.
2. Sew skirt side seams
3. Sew back center seam and put in on seam zipper (see this tutorial)
4. Sew flounce to bottom of skirt
5. Sew facing or lining to waistband, turn to inside
6. Hem

This concept also works if you want the bottom part of a yoked skirt to be fuller than the top part, but without having gathers. In that case, you’d measure the bottom of the yoke, and that would be the top of your curve, and then you’d curve out the bottom – more curve=more fullness.
