This Touching Slate is very useful for the visually impaired.
You will need Velcro Strips, Wool and other odd things to make it.
First apply glue to a thick piece of cardboard.
Velcro has two strips – the hooks and the loops – which stick together. 
Stick Velcro hook strips to the cardboard.
This will be your DRAWING SLATE.

Next make a hole in the base of a film can to pix a pen.
Make a small hole on both ends near the mouth of the can.
Cut a “V” notch in one small hole.
Make a rubber pulley and a Z-shaped wire crank. 
Push the crank in the pulley.
Tie one end of a 3-feet long wool to the pulley.
Cut the back end of the pen and push it through the can hole.
Weave the other end of the wool through the pen.
Pull the pen out further. 

Now fix the crank-pulley assembly in the can.
The Drawing Pen is just like a Fishing Line.
On rotating the crank the wool will wind on the pulley.
Tie a fat knot at the end of the wool. 
Crank to wind up the wool fully.
Now hold the Pen and draw a DINOSOUR on the Slate.
WOOL STICKS TO THE VELCRO SLATE.
You can feel it and know what you have drawn.
Rewind the wool.
Now draw a flower.
This TOUCHING SLATE is a real help for the visually challenged.
