I had seen a while back that someone had put something like this needle case up. I couldn't find it on the board so I just winged it. I glued the black square onto the case with batting on the inside. There is a pocket for my scissors also.
Of course, my son wanted something out of this fabric. I couldn't think of anything else but a mug rug. He's got two of them, one for home, and one for grandmas. He calls them his shooters. I sewed around the gun so it is quilted but it is hidden.
