MIEventer is not wrong
I have been making bridlework for 18 years so I could make you almost anything.
You can have a band made to your design - a plain browband, a V browband, a browband with your designed pattern stitched in to a browband in any colour you want !.
See pics below for some idea - the first pic is of shaped browbands, the second
Is of coloured bands green, blue, purple and red ( as the dyes mix any colour is possible ), the third is beaded browbands PICT0001.jpg PICT0031.jpg All four.JPG
