Pfft...such limited imagination, matey. You should go for the Dean Hoyle/Tony Bloom chairman special. Or see if they do a half-half 'shirt sponsors' scarf.
It's tempting isn't it?
As an aside - what happens with all these scarves that don't get bought? Are they recycled? Can you recycle them? Is there a half-half scarf mountain somewhere where Burnley v Watford 2015 lies forlorn and unwanted next to a Wigan v Sunderland 2013 scarf?
