In Waterstones.
A wee pocket sized spiral book with an inkpad attached. Title was something like 'Things to draw with thumbprints'. It gave you instructions on how to make lots of different things / animals / people using only your thumbprints, and there was space in the book to make your pictures. Kind of like a wee activity book. It honestly looked soo cool. Perhaps for a child over 7yo or adult...
Think is was about £4.
Actually maybe i'll get one for dh stocking. He's not arty at all but likes novelty items. Hmm...
