Step 1: Items Needed
-Old pair of jeans (or other old piece of clothing, doesn't need to be jeans)
-Sewing needle or sewing machine (I used a needle but I would recommend using a sewing machine)
-Some kind of fastener (zipper, velcro, buttons or presstuds)
The following items are not needed but may be useful:
-Pen or pencil
-More material (this could be used to make a patch to personalize your case or add an inside lining)
-Rubber stamp and ink
-Screen printing supplies
Step 2: Cut Your Material
They don't have to be the same size because after you have sewn them together they can be trimmed.
Step 3: Personalizing Your Case and Sew Your Material
I originally planned to use an old T-shirt and make a patch to sew onto the case but then I decided to use the patch off of the back of the jeans.
Choosing a fastener
advantages and disadvantages
zipper - completely seals your case, not easy to sew onto your case, if your pencil case is overloaded it may be difficult to close your case but it will stay shut.
presstuds - hold strong but will pop open when strain is too much from an overloaded case, easy to sew on (if you choose presstuds I recommend you sew them to the outside of the case then fold the edge over and sewn down to hide the messy stitching).
buttons - easy to sew, difficult to close when the case is overloaded but should stay shut unless the stitching isn't very strong, stitching may look messy.
velcro - easy to sew, doesn't hold strong when case is overloaded if your stitching skills are good then the stitching shouldn't look messy but if like me your stitching does look messy you can do what I did and make a flap (this will be shown later in this Instructable) the stitching will only be visible on the outside of the flap but can be covered with a patch. this flap method will also work for the buttons.
Now it's time to stitch the rest of case, make sure you stitching the case inside out then turn it back in on itself this will hide the stitching and the frayed edges.
