I had a hi-viz waistcoat issued by my company but the branding has now changed so I can't use it. I spent an enjoyable hour this morning picking it apart and then sewed up this little pouch using the retroreflective stripes for the outer and the yellow fabric for the lining. Should be easy to find at night if I drop it! Aside from my label and the zip, all materials are from the jacket. You can't see in the picture but the seams inside (which are double stitched) have bias binding from the edging on them
