can someone tell me where i can buy cheap pillow inserts(aside from idea) i also want the rectangular which i don't think ikea have. Looking for zippers as well.

I found some rather good ones in habitat (rectangular) but they were very expensive. I finally found more reasonably priced ones (about 13€ each) in a shop called Euro Diff.

You can get zippers from a "mercerie", and I think Carrefour is a good place for cheap rectangular pillow! Good luck!

Confirm the Carrefour suggestion!
