How To Sew Bias Binding (+ video tutorial!)

Bias binding is a lovely, tidy finish for your makes, concealing your raw edges and neatly tucking them away. It's useful for creating a neat finish on seams that aren’t attached to anything else and don’t have a facing. In this blog post and accompanying tutorial video, I’ll be showing you how to sew your bias binding to the neckline and armholes of our Skye sundress sewing pattern. But this tutorial will apply to any garment where you need to sew with single fold bias binding - woo!

For Skye you want to look for a 10-13mm (1/8-1/2in) wide single fold bias binding, approximately 20-26mm when folded flat, if you want to buy it pre-made, or a lightweight cotton if you want to make your own. If you have some lovely suitable fabric scraps calling your name, learn how to make your own bias binding with our step-by-step tutorial and video. 

With your bias binding ready, let's get into the tutorial...

Take the folded bias binding and start at the shoulder seam or underarm seam if you’re attaching bias binding to an armhole. Leave 10-20mm (3/8-3/4 inch) of binding overshooting the starting point.

Open one side of the folded bias binding and pin in place all the way around the raw edge of your garment, right sides together. If you have stay stitching make sure the binding fold is just past the stay stitching so it’s hidden when stitched.

How to do bust adjustments on a pleated bodice

Do you ever feel like your clothes would fit slightly better across the bust if there was a little bit more fabric, or conversely a little bit less fabric in that area? If this is something you agree with, then you might benefit from doing a bust adjustment to your bodice pattern pieces. 

You may already be familiar with doing adjustments on bust darted bodices, dartless bodices and even on pattern pieces for knit fabrics. But what about bodices with pleats at the waist?

After searching high and low on the internet and in my trusty fitting books, I couldn't find anything that covered how to do bust adjustments on a pleated bodice. As I wanted to do a full bust adjustment myself on my Skye sundress pattern, I knew that other people would want to do one too. So, I had a play around with the bodice, did some testing and came up with a system that has worked for me. I mean that's the best thing about sewing isn't it - you can make your own rules! 

How do I know if I need a bust adjustment? 

There's a technical and a not-so-technical answer here! The answer depends on your own unique shape and the fit of the garment - you may not need to do a bust adjustment to a loose top or dress, but might have to do one on something more fitted. If you find that things are generally either too tight or too loose in the bust area, then I'd recommend making a quick toile of the bodice, or wearable toile of the whole garment to test the fit around the bust and take it from there. I'm going to briefly cover how you would work out how much to add or subtract from your bust in the adjustment, but do remember this is just a rough framework, and you might not need to do it at all. 

Measure your high bust (your upper chest, just under your armpits). If you're making a pattern in our sizes UK 6-24 size band, add 5cm (2in). If you're making a pattern in our sizes 16-34 size band, add 10cm (4in). Choose the pattern size with that bust measurement – this is the size you’ll do your bust adjustment on.

Now measure your full bust (fullest part, around the nipples) and compare it to the bust measurement on the pattern size you just selected. 

If your full bust is 5cm (2in) smaller than the pattern, you’ll be subtracting 5cm (2in) from the pattern; if it’s 7.5cm (3in) bigger, you’ll be adding 7.5cm (3in) and so on. If you need to make the bust bigger, you'll need to do a full bust adjustment (FBA) and if you need to make it smaller, you'll need to do a small bust adjustment (SBA). 

Since the front bodice pattern represents one half of the top, as the fabric is cut on the fold - or one boob - you'll be adding or subtracting half of that difference. So, if you want to do a 5cm (2in) full bust adjustment, you'll need to add 2.5cm (1in) in total to the pattern piece. We're going to add this fullness, or subtract it inside the pleats, you'll need to divide the number of you wish to add to or subtract from one half of the bodice between the number of pleats you'll be adjusting - don't worry if this sounds a bit complicated, there is more info below!

How to Make Your Own Bias Binding

Want to add a pretty detail to your homemade clothes?

Bias binding is useful for creating a neat finish on seams that aren’t attached to anything else. The bias cut will allow the binding to stretch slightly, which is handy for getting around curves such as armholes, necklines and curved facings.

You could bias binding to projects such as the armholes of the cap sleeve version of our Etta dress sewing pattern, the back, underarms and straps of our Fifi camisole, the armholes and neckline of our Skye sundress, and the facing on the unlined versions of the Arielle skirt and Sonny jacket.

You can buy ready-made bias binding relatively easily. But it’s good to know how to make it yourself so you can make it in a print, colour and width of your choice. Homemade binding is one of those details that can make your handmade clothes truly special. It's also a great fabric stash buster!

You'll need a bias binding maker for the method shown in this blog post. But a bias binding maker isn’t an essential tool, as in the video tutorial below I’ll also show you how to make bias binding without one, just using your iron instead - yay!

Here's how to make it...

You’ll need a large piece of fabric – a light- to medium-weight woven cotton will be fine. I'm using a Liberty print Tana cotton lawn. You'll also need a bias binding maker for the method I'm going to show you. You can get these handy tools in different sizes – I’m using a 12mm (1/2in) one (this is an affiliate link), which will make single fold bias binding that is 12mm (1/2in) wide once finished. This size is perfect for binding the armholes on the Etta dress.

If you want to make double fold bias binding, for example to bind a neckline edge where you want the binding to be visible on the outside as well as the inside of a garment, you'll press the single fold binding in half after it comes out of the maker. So you’ll end up with 6mm (1/4in) wide binding with a 12mm (1/2in) maker.

Fitting the Skye Sundress

Making the lovely Skye sundress and want a few hints and tips on fitting? Well then, this post is for you! Skye is perfect for stitching newbies as it’s easy to sew and fit – yay! This post will cover the most common fitting adjustments you might want to consider for your Skye dress. However, don’t feel like you need to do them all, or even any at all!

Skye is available in printed and PDF formats sizes UK 6-34 / US 2-30 / EUR 34-62 / AUS 6-34.

Skye has an easy-fitting empire waist bodice, which is gently shaped with bust pleats, and the neckline and armholes are finished on the inside with bias binding. The neckline has a gorgeous, slightly square scoop shape, and is designed to cover a bra, with a flowy, gathered skirt with mini-, knee- and maxi-hem lengths to choose from. Of course, there are deep in-seam pockets too!

We sometimes recommend that you make a "toile" (or "muslin") - a practice garment in cheap or spare fabric in a similar weight to the fabric you're going to use for the final garment to test the fit - however, it's not strictly necessary here. If you're unsure about your sizing and have some expensive fabric lined up to make the dress in, you could make a quick toile of the bodice to check the fit, leaving off the skirt. However, if you don't feel overly precious about your fabric, then go for it!

• Choosing your size
• Lengthening or shortening pattern pieces 
• How to combine pattern sizes 
• Bust adjustments
• How to do wide and narrow shoulder adjustments
