Sewing project - Range finder cover

I've had this range finder since I was playing on tour.  So that's perhaps as early as 2005?? So the range finder AND this cover is at least 20 years old!  And as you can, it's definitely seen better days:

We have plenty of fabric from Graham's old jeans. He keeps putting holes in them!

So glad the pocket of the jean was the perfect size to fix up this cover.  A little bit of elbow grease with the needle and thread, and TA DA!!!

The buckle/clip is still broken and I could not break it off.  So it will just have to be for now. Let's see how much longer this will last!? :-)
