How to Repair a Tear Inside a Backpack

First use the scissors to cut off the destroyed nylon material inside of the backpack.

Using the ruler cut out the propitiate length of nylon material to cover the tear inside of the backpack.

Use the push-pins to hold down the corners of the material.

Put thread through the needle. Double knot the thread to secure it on the needle. Then cut the end of the thread and double knot the end as well.

The stitch to use for this repair is the basic stitch. To do a basic stitch just poke the needle through the nylon material until it is on the other side. Bring all of the thread through. Then push the needle back near the thread that was pulled through.

Repeat doing the basic stitch. Keeping sewing until all of the nylon material is secure. This picture is an example of how a basic stitch row should look like after repeating the stitch.

Once finished cut the remaining thread and double knot the thread. Trim off any excess nylon material that is not sewn down. This is the finished product.
