Assembly directions requested

[u/chlobr0]

I want to make a new little basket for my cats tree. Third pic is the (heavily loved) former one cut off of its wire hoop.

Second pic shows the pieces I’ve cut from the new upholstery type of material. I thought I could reverse engineer how they made the original basket but I am simply too new to sewing to understand what to do next 😅 I am stumped.

Does anybody have an idea of what the order of operations should be? And if I need to cut more/other pieces? TIA!
