Like everyone else I get a lot of junk mail and it usually ends up in the recycling bin. But I had an idea to see if I could make something with it instead of just throwing it in the bin. So I came up with this, I made a letter opener from the junk mail using fiberglass resin to make it stiff. It is basically the same as making Micarta from fabric but instead I used the paper from my junk mail. The process is fairly straight forward and the end product ended up working quite well. I don't know how long the edge will last but I only plan to use this for opening letters so I'm not too concerned with it becoming dull. And if it does become dull I can always touch up the edge.

The first thing I did was gathered up some junk mail that was all about the same size.
