A weak year turned around inside a quarter
June to August 2026 revenue was up 152% on the same months of 2025, and July 2026 was the strongest month since December 2024. In 2025 the account had been running flat.
Two formats doing the work, and a new range landed
The A5 concertina sketchbook is up 49.5%, the A5 travel journal 71.1%, the Square ’n’ Chunky hardback 34.2% and the A5 black concertina 85.7%. Concertina and travel journal formats are the clear winners.
A water-mixable oil paint range also started selling this year from zero. A small advertising test ran at a 20% advertising cost of sale, and knowing which formats convert makes the case for widening it.
