I have been using these for making button brooches and bouquets.
Also great for knitwear projects and bag fasteners.
These are size 54L which is 3.5cm or 1.25inch
I also have GIANT mint buttons...
Also available in bags of other colours and larger quantities.
see www.LovePaperFish.com for more buttons
or... http://PaperFish.etsy.com for all my big buttons turned into party favor brooches.
