To some it's a giant nylon spider's web, to others it's a 12ft doily.
Whatever the bizarre art statement is, bemused motorists have no idea how the rogue knitting project turned up beneath an underpass in Bristol.
The huge spider web under Stapleton Road railway bridge in Bristol is believed to be the work of 'yarn bombers' or 'guerrilla knitters' - street artists who make decorations by knitting or crocheting wool, or turning yarn into pom-poms.
The huge doily was spotted by Gail Boyle as she drove into work on Thursday morning.
'I've no idea who is responsible, it might be 'yarn bombing', but I crochet and I know that they are proper crochet stitches,' she said.
'It's a massive piece of crochet and the nylon cord must be up to an inch thick.'
Last year guerrilla knitters in Bristol made a huge cloak for a Queen Victoria statue in College Green.
'This latest piece of guerrilla crochet is beautiful - it shines like a little white beacon,' added Gail.
