I have a hazy memory of the original Fert CAD working having branded sacks, but I can't find the image on the site to confirm.
I also have a hazy memory of somebody, possibly Dive Controller, subsequently asking about the change, and one of the lads, possibly warbonnet, saying that they'd had to revise the loads and leave the logo off.
Also possible that it was all a dream.
But yeah, I'd definitely buy a few stickers for my unbranded pallets.
