Sewing a boho pouffe - where to buy filling online?

[Startingagainandagain]

My next sewing project is a small boho pouffe for my living-room.

Could anyone suggest where I could order online some polyester filling for it?

I am hoping to make something like this:

I use textile off cuts

Thank you for the link!

It could quite heavy if using stuffing and would need a lot ! When I made one similar I filled it with layers of circular cut foam.
