As noted in my update to the DIY Landing Net and Fish Bag Post the method of connecting the straps to the bag by putting them through the hessian was starting to wear.
So I resorted to an idea I remembered from the Golden Book of Camping. I put a marble in each corner of the bag and used a cable tie to secure it. I then attached the straps to the tie. This should be a more permanent solution.
