Yep, I was actually asked that question - "Can you knit a poster?".
Not one of my more common requests I must be honest, but as you all know I do love a challenge :)
The brief was to do a poster sized piece of knitting to promote the "3 for 2" promotion we have on wool at the moment in Hobbycraft.
The colours were chosen for me, but I did push for chunky wool, as it would have taken ages in double knit.
So, first, I had to design the pattern. I opened up my bead designing program on my laptop and set it to 'square stitch' (I also have a cross-stitch designer program which would have done the job just as well).
It took me a good three hours of fiddling about with little dots to get it right. I decided on 100 stitches and 150 rows.
Each row took just under 6 minutes, making a total of 900 minutes for the whole piece (or 15 hours). But that didn't include the three times I had to unpick it as I was concentrating more on the TV !!
And to show you just how big it is, here is the Hubster holding it up :)
