I bought a bag a couple of months ago that was made with incredibly soft leather. That was the main thing that attracted me to it. It's a great size and I love the color. But after using it for a number of times, I found it annoying that it doesn't keep its shape. The bottom of it has feet, but it still "sags" down when I put stuff in it, no matter not light it is. I have to really stuff the bag to the max to prevent it from happening. Is there anything I can do to reinforce the bottom of the bag, so it can't look its shape so easily? Any thoughts would be appreciated!
