An activity book by Johanna Basford that mixes coloring with drawing. It has one rule: work in the book for at least 10 minutes every day for 30 days. Apart from that, you can do the lessons in any order and as many as you like.
The pages combine drawing tips and ideas for coloring, so each day brings something different. The motifs include flower fields, sweets, bouquets in full bloom, and sometimes robots and stationery.
