What do you need to sew bags? Just a sewing machine and pretty fabric? or not? If you make bags as a hobby or it is your whole career – By the time you have made the first few bags, you would have come to know that sewing bags is awesome and habit forming. And that the right material and hardware play very important roles with almost equal importance in making your bag beautiful and functionally appropriate.
Here are the most important bag materials as a list. Equipped with these bag making materials you are sure to continue making many many beautiful bags.
Essential Bag making materials
Webbing

Bag handles are usually made of the bag exterior fabric itself. But webbing made of nylon/cotton fibers makes it very convenient and easy to make handles. They just need to be cut and attached. The side edges of webbing are already neatly finished and they are quite strong. Webbing is available in various widths and many colors.
Check out this post on the 7 different types of Bag handles.
5. D rings & other rings

A D shaped ring is the most commonly used hardware in bags to hang the straps.

Rectangle rings, oval shaped rings, square ones are all used, depending on the straps/handles.

6. Sliders

These plastic or metal rings with a divider in between helps to increase or decrease the length of the straps.

7. Zippers

Zippers are commonly used for openings in bags /purses and bag pockets. Long zippers with two zipper pulls, one with metal zipper teeth, plastic ones, all are used to make bags.

Here is a post elaborating on the different types of zippers available.
Zipper pulls

You can personalize the regular zipper pulls with pretty accessories or making customized zipper pulls like in the picture.
Zip heads can be purchased seperately and inserted into zip cloths that you buy in bulk – very cost effective if you are always sewing bags with lots of zipper openings. Zip cloth is sold by the yard, with matching zip heads to assemble custom zippers.
Rivets

When you want to attach something on bags like handles , without sewing, you have no substitute for these. Learn how to attach metal rivets here.
Swivel Snap hooks

These are used to attach the straps – the straps can be conveniently removed and used when needed with the help of this hardware.

Magnetic snaps

Another popular opening used in bag making- this consists of two parts, like the regular snaps but because of the magnet used in these snaps they are suitable to close even the thickest of fabric flaps of your bag.
Purse locks

This refers to the locks placed as closures on bag/purse flaps by the front.
Bag bottoms & feet

Bag feet are small buttons placed on the bottom of bags on all four corners of bags so that the bag material would not touch ground.
Purse chains

This is a type of handle made of metal chains. Check out this post on Bag handles for learning more about the 18 different kinds used in bags.
Frames for purses

The frames give structure to a purse and serve as the closure as well and at the same time give an elegant look. Frames are available in many styles, colors, shapes, and sizes. The clutch frames may be rectangle-shaped or arch-shaped, made of plastic or metal. The metal frames come in different colors – silver, gold, antique brass, rose gold, and gunmetal finish.
Very simple ones to the most ornate purse frames – we have seen it all.

Some purse frames come with a ball closure, some do not have this – they just snap close. This is also called kiss clasp.

Embellishments
Different decorative elements are used to embellish bags – including embroidery, applique.

Metal studs are also used regularly on vinyl and leather bags as accents.

Charms can be added to the bags to decorate them and personalize them. Metal labels can be added to the bag front to give your bag a highly professional look.

A buckle is mostly used as an accent.

Grommets and setting tool

If you want to add eyelets /grommets on leather or pleather you need not buy any special tool – but if you have it, it can make a whole lot of difference; especially if you have to make a lot of them.
Pliers
You will need a plier very often while making bags to squeeze and fix small hardware parts like rivets, snaps, and eyelets. Flat-nose or combination pliers are handy when attaching metal fittings without scratching them.
Gum
I am talking about stronger adhesives like rubber cement (which you will need in layering leather and PU) and even temperorary glues like the glue-stick. And a brush to apply the gum.
Fabric protective sprays
There are sprays available which act similar to fabric finishes in creating a protective layer on top, even make the fabric waterproof, scratch proof, soil/stain proof. You may want to add it to protect your bag exterior from scratches and other damages.
Liquid starch
Liquid starch sprays are used to make fabric stiff and crisp looking.You can dilute the liquid starch in a ratio of 2 parts water and 1 part liquid starch and use it in a spray bottle to use on the bag exterior fabric to make it stiff. But ensure the bag would not be washed – then this will wash out and you have floppiness unlimited.
Velcro
The usual fasteners like magnetic snaps are alright but sometimes a length of Velcro makes a lot of sense to close openings on bags – you just need to sew the tape on your bag.
Hammer
I have found a hammer handy for flattening thick seams, setting rivets, and fixing eyelets. Just remember to use them with a block to avoid damaging fabric.
Sewing tools
Needles
Needles starting from sizes 16 going to 23 are absolutely necessary unless you want the needle breaking at every other seam.
All the above are mostly specific to bags. All the sewing tools needed for sewing bags remain the same as those used for general sewing. Check out the post on the different types of sewing tools and equipment you need to start your sewing. And the different sewing techniques used here.
Leather sewing kit
If you want to make bags with leather you need appropriate tools to sew leather. There are sewing kits available with needles and thread and other tools needed to sew leather. You can have a look at the 30+ tools/materials used for hand sewing leather.

Aside from the sewing tools like special needles and thread you may also need a tool to make holes on leather, a Leather edge coat to seal the leather edges etc.
Bag fabric

The material with which a bag is made can make or break the appearance of the bag. In fact, as you know, it is almost the whole bag. So choose wisely. The important criteria in choosing the fabric for making bags is that it is sturdy and durable, has the appropriate structure, and looks attractive. The most frequently used materials are canvas, vinyl, leather, pleather, etc

Lining / Interlining
Interlining is added to give a padded feeling to your bag and gives a slight 3 D effect. Think a quilted fabric. Other than the usual padded interlining fabric, other materials like foam, fusible fleece and batting are added as interlining.
Many professionals add chip board, a somewhat stiff but soft board made of recycled paper inside their bags to give structure. If you want more structure you can use a medium texture board ; it is slightly firmer than chip board; It is used for structured handbags, boxy totes, or clutch covers to keep shape.

Interfacing
There are only a few bag fabrics that do not need interfacing (like leather, fake leather, vinyl, thick canvas). All other fabrics need some interfacing to make them look good enough and with enough structure for making bags.
Fusible / sew-in interfacing is added to the bag fabric to give it body and strength. Choosing the right one is mostly dependent on your choice of fabric for the bag.
Fusible interfacing is attached to the fabric (both exterior and the lining) with heat to the backside of the fabric and is available in different thicknesses, even as thick as canvas fabric. Sew-in interfacing is usually thicker and is used similar to underlining in garments. Use woven interfacing for cotton fabrics.
Sewing machine
Even though a sewing machine is not a material but an equipment, I have included it here because an appropriate sewing machine is essential for the success of making professional looking bags. If you are making bags as a profession or with passion you cannot do so for long with the regular home sewing machine – especially if you want to work with beautiful fabrics like leather, canvas, etc.
It is simply going to frustrate you to no end and you will get only substandard results even with all the sewing expertise in the world or the best of sewing materials. An industrial sewing machine which will sew through all the layers you want is an asset in making bags
