I've been away for a while, in Kesudalen and various other places. Found this cute little pin in the cabin, I think I'll have to whip up a few sketches for something blue to wear it with. I picked up the buttons earlier this year, vintage SL uniform ones. During the first half of the 20th century SL was split into different divisions for different kinds of traffic in another way than it is today, these belong to the one or other of the uniforms for electronic rail division, IIRC, but I have to look it up. I like them, but four is such an awkward number for buttons, I must look around for more of them.
On a fabric in that great, vintage SL shade of blue, perhaps?
Edit: not SL, SJ - don't know where my wits went begging. Oh, well.
