We got them in Tesco today. £8.
I have used the mistake to my advantage and got dh to "help" me figure out what to do with them. They claimed to be 10m which was the length we needed. Obviously, for our purposes, they are only 5m. Dh got so annoyed he announced we would have to buy different ones.
I have draped them artfully across the mantelpiece in the lounge. I will now be allowed them in the sun lounge and over the mantelpiece too. Mini victory for parsnips. Yay!
It will also mean that I now need the pine needle garlanding for the mantelpiece as well (to wind the lights through of course).
I am queen of turning things to my advantage
