*Comes to CCE after giving up on Google*
Does anyone know where to buy a roll of sew-on Scotchlite in Edinburgh? I'm not that familiar with sewing shops, but that seems to be the likely source.
I'll settle for adhesive tape, which my Googling suggests is more to be found at lorry supply type places. Given what it's for I'd probably end up with enormous amounts of it, but that's the opposite of a problem; I'd simply give it away here or(subject to legal advice if anyone wants to donate some) go on a white-hat vandalism spree across the city doing things like hi-vizzing the slalom gates on the canal.
If not, it's the interweb, but that's a faff for a one-off purchase.
