this post a while ago by My Poppet and fell in love with the scrappy felt fabric. I had loads of scraps from various projects and decided to try something similar but ended up going in a slightly a different way. I think its called Crazy Patchwork?
I put together a few of the scraps and needle felted them together at the ends to fuse the fibres (I knew I would have trouble with machine stitching if they weren't attached a little!). I measured the case and worked out I needed two pieces approx 18cm X 10cm each.
After felting the pieces, I used a zigzag stitch in black all over each of the join lines. It was a bit rough in places but I have decided that adds to the effect!
