I've laid out all the parts for the XOR Goat, they take up five sheets of A4 card. I printed them out twice, once on card, once on paper then scored and cut out the card version. Then it was a case of assembling the model and making up gluing numbers and corrections on the paper sheets.
I'm pleased to report that the completed model works as intended.
Colour tomorrow. Off to make a hot honey and lemon for my True Love who now has my cold.
