I had a lovely experience today whilst visiting the National Roman Legion Museum (Amgueddfa Lleng Rufeinig Cymru) in Caerleon with my children.
I grew up nearby and I'm pretty sure that there are not a vast number of Welsh speakers in Caerleon, so I was really pleased to find that the kids quiz/treasure hunt sheets were available in Welsh and that I could have a chat about it to the nice lady on the desk who I knew spoke Welsh because she was wearing a "Iaith Gwaith" lanyard.
I was really pleased to be able to inflict some of my under-practiced Welsh on her and she seemed genuinely pleased to be having a little bit of sgwrs yn Gymraeg.
Which brings me on to my point - I often wear one of the orange Cymraeg badges from the Iaith Gwaith scheme of the Welsh Language Commission. Often people will spontaneously talk to me in Welsh when they see this and I do the same with others.
For any of you who want to be similarly "branded" to elicit sgwrs from complete strangers, you can find some free resources (badges, lanyards, email footer) here: http://www.comisiynyddygymraeg.cymru/hybu/en/assistance/Pages/assistance.aspx
It's mainly aimed at businesses who want to/should be offering welsh language services, but there's nothing to stop anyone from ordering badges etc as far as I can see. The email footer etc is a free download.
I have a load of the badges myself and might bring them along for the table at the SSiW party, if anyone wants one...
A bit similar to an earlier thread -
