It would be nice that there will be some bags or baskets, thats have a weight based inventory just like your character.
At this point the reed basket is quite unusable, so if you replace the inventory for example to can hold 2.5kg stuff, more likely the people will use them.
*UPDATE*
Maybe you can place objects what actually have weight, so you cannot store seeds there.
My idea:
Reed basket - same recipe - 2.5kg capacity
Bark basket - 15 bark fibre - 5kg capacity
Leather bag - 4 leather 2 fibre 1 raggy hem - 10kg capacity
Cotton cloth bag - 5 cloth - 2 f1bre 1 enforced seam - 15kg capacity
Egyptian cotton cloth bag - 5 egyiptian cotton cloth - 2 fibre - 1 Amber Coarse-Grain Thread - 20 kg capacity
Personal bag - 5 see island cotton cloth - 2 fibre - 1 Embroidery - 25kg capacity - can be locked with a lock, but easy to destroy.
Theese stuffs not well considered, but with adjustment can be works.
