Free Guide: 5 Mistakes Collectors Make

    A concise guide to the five decisions that undermine great buying and the simple habits that solve them.

    What you’ll learn in 10 minutes

    • How to choose for your space rather than the moment, with a simple visualisation check. (see page 3)

    • The two-thirds proportion rule that brings instant cohesion above furniture, plus a pocket measuring kit. (page 4)

    • A colour approach that creates harmony with depth, using cues from stone, timber and textiles. (page 5)

    • A context test for light, placement, and the company a piece will keep. (page 6)

    • How to read quality independently of price, training both eye and hand. (page 7)
