Step 4Backplate

Backplate
Measure the approximate dimensions of the inner pocket (should you have one). Then cut a slightly larger backplate. Cutting the four corners off will make wiggling it in a little easier and reduce any stressed points inside the bag as bag corners tend to be rounded, not square.

If you absolutely can't fit the backplate in, trim it down.

The backplate is necessary to hold the bag's shape. Without this, the support hooks are free to move making the bags insecure.


If you don't have an inner pocket - follow the same instructions, but don't make the vertical dimension as tight. The difference in manufacturing bags with inner pockets versus without will be start in the following steps.

I used an old LP as a backer board... Make sure no one wants to listen to it anymore, then it is effective reuse! It is easy to shape if you score the surface and then snap it. I then sanded the edges so as not to poke through the bag.
