2" bias binding

[to-my-wife.livejournal.com]

I'm making a blanket for a good friend's baby due next month (black butterflies stencilled on a soft pink floral background) and need some 50mm/2" double fold bias binding to finish it (I want 1" showing on both the back and front of the blanket). I am finding it impossible to track down! I've come across bias binding makers in those dimensions, but I don't want to make it myself.

Can anyone help? I'm in the UK but am willing to buy from anywhere providing the price is reasonable. I'm looking for either black or pink.

Thank you! <3

P.S. Even 1.75" would do!
