In January 2003 after trying to find a badge to say I could be of help to others using BSL, and finding nothing, I designed a car sticker and found that they were well received. I then used the same logo to design lapel badges and mugs.
The badges are designed to be used by people who can sign at the standard of BSL level 1 or higher. By wearing a badge you could be of help to other people whose first language is BSL. The badges are now in full use all over the British Isles.
