On the seventh day I suggested to Eilir that I demonstrate the 'ancient art' of potato printing for the purpose of making our own homemade wrapping paper.  This age-old tradition (I explained) is what I used to do in school in the days before mass-produced, ready-shaped, painting sponges.  I think he thought I'd gone mad when I brought out the potatoes and started cutting them in half!  I kicked things off by cutting out a star shape, Eilir then had a go at scoring out a Christmas tree shape and a holly leaf shape.  After letting him loose on the knife for a short while, I then took over the fiddly bits in order to prevent bloodshed.  I made a little berry shape to go with the holly, which Eilir was unsatisfied with, so he produced a double berry design of his own that worked much better.  Eilir was in competitive spirits and wanted to better any design I created, so after I printed a bunched holly design, he printed a wreath shape using the holly spud print and announced "Definitely better - a whole circle".  He also played with different effects - dragging the star spud across the page saying "Look! It's a shooting star!"  Great fun and very messy.  We hung the sheets up to dry, and were able to use them for wrapping presents that we delivered on Sunday - Eilir was very proud.
