May I introduce 'I Believe in Unicorns' A Colouring Book by Sarah Lovell.
This beautiful book is completely hand drawn , and features 20 detailed illustrations for your mum's colouring pleasure. Each picture is also accompanied by a positive affirmation to fill her day with happiness and positivity. The book is spiral bound so, the 'Carbon Captured' paper pages can be easily removed and displayed once coloured.
