The Odd One Out

It's one of those days where I went out early - A day volunteering in the Glamorgan Archive. On finishing caught the bus home, had tea and flopped in the chair.

Oh dear , no image today - what's in the workshop? I've got a new piece of black cloth I bought last week, a bag of runner beans collected when I cleaned up the allotment and a box of electrical bits.

Can you spot the odd one out?
