How to Sew Bag Straps

 

There are several factors to consider when making fabric bag straps, width, the suitability of fabric and interfacing.  Bag hardware comes in several standard sizes, often  3/4″ (18mm), 1″ (25mm), 1 1/4″ (32mm), 1 1/2″ (38mm), 2″ (50mm).

Choose hardware that suits the size of your bag, for example, a thinner set would be suitable for a wristlet bag.

Next up the choice of fabric and interfacing to go with it. The bag strap I am making is with a canvas weight fabric with fused heavyweight interfacing. For a lighter weight strap, you may choose a quilting cotton paired with Pellon SF101 woven interfacing. You may prefer a heavyweight fabric that requires no interfacing. Take a few minutes to check how your interfacing interacts with your fabric,  fold it and see how it feels and how your sewing machine copes with the layers of fabric.

Measure the inner width of your hardware, this will be the width of your finished strap.

Cut your interfacing and fabric four times the width of the desired finished strap.

Fuse the interfacing to the wrong side of your bag strap, following the manufacturer’s instructions.

Fold the bag strap in half, wrong sides inwards. Press with a hot iron.

Open the fabric out, fold the long edges into the middle pressed line.

Fold again, this time you are folding the right sides together, so the strap is inside out.

Stitch across the short end, both short ends.

Now for the magic, turn the strap the right side out to discover your super neat ends.

For many of us making bags adjustable crossbody straps is an essential skill to our bag making knowledge. But just how do you attach a slider? How do you make the strap? What about a pretty strap or a masculine strap? 

How to make an Adjustable Bag Strap

Before we start on how to make the adjustable bag strap decide the material you are going to use.

Cotton Webbing – available in a variety of thicknesses and widths. Often available in a plain color you can, with searching, find striped webbing. Personally I love to jazz it up with bias binding stitched to one side. I have made my own bias binding out of the lining fabric and added a strip to my adjustable bag strap.

Nylon Webbing – Super strong you often find this in shop-bought bags. I often choose it when making a bag for a man. The material can fray easily, a way to prevent this is to melt the cut edge very carefully to deal it.

Fabric – Choose a close weave, pair with a suitable interfacing to provide a strong adjustable bag strap.

The beauty of making your own adjustable shoulder strap is you can make it a length that suits you.

 

I have just finished making myself a denim messenger bag from a khaki pair of jeans. Check out my free denim messenger bag pattern.

Whilst making this bag I chose to sew the adjustable shoulder strap from cotton webbing complimented with bias binding made from the lining fabric. To make your own bias binding, cut strips of fabric at 45 degree angle (a quilters ruler usually has this angle marked, super helpful). Thread through a bias binding gadget and iron.

You will need two rings and a slider, with the internal width of the bag hardware equalling your strap width. An average strap length is 52″, with two side tabs at 5″ each.

  1. Attach side strap tabs

Cut two pieces of side strap tabs – mine are 4 1/2″ each. Slide on your rectangular ring and fold into a loop. Place on the side panel of the bag, ensure you are not stitching too close to the top of the bag, as it is usual to do this step prior to inserting the lining.

Sewing through thick layers of fabric can be tricky for your sewing machine. Use a strong needle, a long stitch, stitch slowly and use a walking foot if you have one (this helps all layers feed through the machine evenly). 

Do not forget to backstitch.

You can stitch a rectangle to secure the strap but I prefer to stitch a rectangle with a crisscross.

       2. Attach the strap to the hardware

Thread your strap through the slider. Fold the end under, pin and stitch to secure. I like to stitch a rectangle.

Take the other end of the strap and thread it through your rectangular ring on the side strap tab. Thread from the inside of the bag to the outside with wrong side upwards.

Now taking your end of the strap thread right side up through the slider.
