Hello,
I had ordered some 2.7mm stringing line (deck planking) from Craft Supplies, 15 packs of 10x1m.
Unfortunately some widths were undersize, I phoned them, and they were just so helpful, sending me 80m free of charge, & I can keep all the undersize strips.
The company is - craft-supplies.co.uk, and they do widths of 'stringing line' at 1.5mm, 2.7mm, 3.4mm & 6mm

At the forth attempt to send me what I wanted, they finally gave up and said they were out of stock. I am now getting it from Modelling Timbers.
The phrase about counting chickens springs to mind.
