My bags look way worser than that.
The bottoms got mostly disattached near the frame so put reusable plastic bags in them to prevent smaller things falling through.
At some point I repaired that, I drilled 3 mm holes along the seams, every 15 mm or so, in both bottom and inner side, then with a bigger needle with thick nylon thread I sewed forth and back through the drilled holes. A knot at the end, but nylon is stiff, so to prevent the knot untangling, I used a cigarette lighter to ignite the ends so they burnt towards the knot then I blew the fire out and pushed the molten drop flat, as a stop to untangling.
And bingo, back in business.
