Eight adult colouring pages, each a single floral mandala about 170 mm (6.7 in) across, centred on the page with a small title in the footer. They rise in detail as you go: the first two are eight-fold with broad petals and big spaces, the next two twelve-fold, and the last four sixteen-fold, adding layered petals that tuck behind one another, scalloped rings, dot rings, teardrops and woven lattice bands. Page eight has more than three hundred spaces to fill.

The lines are a soft plum-grey rather than black, 0.85 pt for outlines and 0.6 pt for inner detail, so they guide the colour without shouting through it. Every enclosed space is at least 2 mm across, so even the smallest can be filled with a sharpened pencil or a fine-tip pen.

The pages print as line art; the card shows one coloured in. They suit coloured pencils, fine-liners, gel pens and alcohol markers (put a spare sheet behind the page for markers). Print on heavier paper if you like to layer colour.

You get two print-ready PDFs, one for A4 (210 x 297 mm) and one for US Letter (8.5 x 11 in), plus the font licence. Eight pages per file, one mandala to a page. Set in Fraunces and Mulish, in a soft plum-grey with pale peach, lilac, butter and sage tints, fine single-line botanicals and small four-point sparkles.

How to print: open the PDF and print at 100% ("Actual size"), not "Fit to page", so the sizes and spacing stay true. Choose the A4 file for A4 paper and the Letter file for US Letter. Everything sits at least 10 mm inside the page edge, so a home inkjet prints all of it. The pages are line art only, light on ink.
