where to get organza ribbon

Hi, I'm going to try make the bows for the end of the pews. Is there anywhere in Ireland I can get it? Or am I better off on Ebay - it's hard to tell from the pictures how much I would need. It's a small church not sure how many pews as of yet. What width would the material need to be? Thanks I'm dying to get going on something!

I got it from ebay, seller was balloonpartysupplies It's 70mm wide and I bought 20m which is making about 12 pew ends as our church is small so don't need any more than that.

thanks a mil - that was who i was looking at :D
