Here's A Weird Find

This I actually found when I was washing my car. The hose was on the ground under a bush, and pressure of the water flushed away some of the dirt. I went to get the hose, and noticed a piece of cloth half buried in the mud. I pulled it out of the ground. I had to dig a bit since the cloth was buried deeper than I thought. This was wrapped up in the cloth. The cloth looked like just any old torn piece of shirt, so that got thrown out. I am wondering if it is part of a button or something.
