Make your own tablets:
Any cardboard with a smouth and even surface can be used. Here I have taken two milk containers, but a set of playing cards could serve the purpose as well.
Furthermore you will need a marker, scissors and a ruler.
Cut up the containers and cut out squares of 6 cm X 6 cm.
When You have 12 squares of cardboard it is time for cutting holes.
Place the holes in the middle of the corners of the tablets – if I place the tablet 1 mm outside the side edge of my cutter it places the hole at the right place.
Now we are ready the make the warp.
