For the bigger walls of the Castle base (The middle part) you will need to measure and mark down 20cm x 12cm on a piece of cardboard and cut it out with the scissors. After cutting out the piece of Cardboard use it as a template to cut out another piece of cardboard the same size.... Now, to form the drawbridge, poke two holes 5cm apart near the middle of one wall. From the hole, cut 8cm upwards and cut the 5cm left and back down 8cm (DO NOT CUT RECTANGLE SHAPE OUT). You should now have a flap sticking. To make this Drawbridge work you will need to tape your string to the back of the drawbridge and poke small holes in the castle base, to fit the strings through. Now, tie a knot in the string and you should now be able raise and lower your drawbridge by pulling the string.
