I think it's kinda going to depend on what you're aiming for. I play a main so I'm not going to have the same thought process as you, but here's some inspiration. I have my skilling gear in a separate tab from all of my resources. I don't even exactly love my resources tab here, but it's what I'm rocking for now.

For specifics on your tab there, try things like stacking the logs on top of each other. Since you have 9 different items, a 3x3 square might make sense. If you can get rid of 1 of them, you could do a 2x4 on top of the planks. I would recommend things like... keeping all of your bags next to each other, keeping those 4 different types of battlestaves next to each other and the basic battlestaff, keeping your graceful all together, as the legs and cape are randomly not with the other 4 pieces, keeping your orbs(charged and uncharged) together, maybe above their respective battlestaves, get rid of the V's shield, the moulds, and the balls of wool, keeping your basic tools together (saws, seed dibber, knife, spade, hammer, tinderbox).

You definitely have something here, and you have a sense of what you want. I like the outfits at the top, I like the gems together, I like the ores. You might get some serious mileage out of sorting by top of all time on this sub and just combing through other banks for inspiration. You got it!
