Thank you, you lovely lot. You've given me a lot of laughs and made me realise I'm not the only one with 'problems'!
instagran I did look up the meaning of pedantry before I wrote as I didn't want to use the wrong word -
pedantry
ˈpɛd(ə)ntri/Submit
noun
excessive concern with minor details and rules.
"to object to this is not mere pedantry"
Haha, I must have OCD after all! 
baggs, you're right, I am pegantic!
Anyway, the upshot is I'm going to give all the coloured pegs to my daughter, who doesn't give a fig which peg to use, and buy myself some more wooden ones. I just hope they are the same colour as my existing ones
