This is a response I made to person from

There are different kinds of cases. A soft or semi-hard case is flexible in that you can fold it or squeeze it flat. A hard case as pictured on my website is rigid.
For the soft case all you need to do is sew the liner in such a way as to have separation between the parts. The butt or lower part of the cue is generally 1.25" in diameter at the widest part and the shaft is generally about .75" at the joint section and .5inch at the top. most cue case makers sew the liner and attach it at the top opening of the case.
Making a rigid tube case as pictured on my site is achieved by wrapping the leather around individual PVC tubes or even around one single PVC tube with a cloth liner.
Using individual tubes is often easiest. Simply get them from the hardware store. Plumbing tubes for the butt and electrical tubes for the shaft. I don't know the common sizes of tubes in inches. I use tubes that are about 40mm for the butt and 23mm for the shaft inside diameter.
You will want to sew some sleeves of soft cloth. Not too tight. Run them down the tubes and bring them back over the ends. Use packing tape to secure the cloth and leave about 1" from the top down with no tape on it.
Now tape the tubes together in the shape you want.
Now you have your core so you can decide which way is best to wrap the leather around it. One way is to make a soft case and stuff the tubes into it. Check out this guy's website for a few examples of such cases -
www.nittanyleather.com He makes a basic envelope style case with tubing inside.
The most important thing to remember about cue cases is that the cues should be protected from scratches and they should be easy to remove and easy to get out at the very minimum. If you put a side handle be conscious of balance so that the case carries well with the cue inside. The handle will not go in the center of the case as the cue is heavier at the bottom.
What we do is a little more complicated than this but what I have told you is the easiest way to make a cue case.
If you have any other questions please don't hesitate. And good luck. I am sure yours will be better than my first one.
