Create a Hybrid Instrument Casing

Create a Hybrid Instrument Casing

The most popular instrument cases sold in the market are the hard-shells, According to Tapestry Shopping, there are also cheaper ones, which are the instrument bags. In hard casings, manufacturers install the interior of the cases with pads to help keep the instrument in its shape. They do it by using plastic and foam, which is done in their factory, and it adds up to the price of each case. However, you can save more money by doing it yourself! – And here is an article that can help you in creating your own instrument casing.


Here is a step-by-step procedure that you can follow in creating your own instrument casing.

Designing the Case

The first thing that you should do is drafting the case. Do it by placing your instrument on large cardboard that is large enough for you to draw its outline using a marker. When you’re done with the shape of your instrument, draw additional guidelines of the casing that fits your instrument.

Cutting the Foam

When you’ve already cut the shape of your instrument casing from the cardboard, use it to draw outlines on the foam that you want to use for the case. EVA foam would be a great choice. It is dense and strong enough to help your bag become stiff. After that, transfer the pattern, cut the layers, and then try layering them up.

Lining the Interior

Find a fabric that you can use. You may choose a wool type, velvet, or tapestry. Tapestries are also good because they have beautiful patterns, so if you do not have any, you can go tapestry shopping. You should use fabric in your case in order to avoid scratches on your instruments.

The process for this is just like box lining; however, the space is not rectangular. What you have to do is to cover all the surfaces. When cutting the fabric, make sure that it is oversized. Cut the edges in order to grade the fabric over all the edges. Use adhesive to cover the foam with fabric.

After that, snip long thin strips, and stick them along the surfaces that are vertical. The strips allow you to hide the folding and snipping in order to completely cover the surface.

Stitching the Outer Cover

The initial process for the outer cover is by creating the sides. Do this by measuring the height as well as the distance to its split. If the thicknesses of your EVA foam pieces are equal, this step will be simple, and it will just be flat when you open it.

For the zipper, baste the inner pieces, press them flat, and then place your zipper at the centered of the seam. The exterior cover should lie over the tape of the zipper, and then stitch it.

After that, wrap the complete sides around the whole case, and let them be fastened using pins, and ensure that the zipper is still at the center of the seam. You can then proceed in stitching.


After the completion of the outer shells, you should glue it around the foam case. Make sure that the outer casing conceals where the lining was cut and folded over the edges of the foam. The edgings only need sufficient support to prevent it from flopping when the case is opened. Use adhesives or super glue to fasten the bottom and top faces. Make sure that when applying glue, you should avoid the zipper because you would have problems opening it.

You’re all set!

This is the simple process of creating your own instrument case. You may also add accessories like a bag handle or strap for easy carrying. You can just easily do that by stitching them. Make sure that the glue is dry and everything is perfectly fastened before you proceed in using it.
