Phyllotaxis Paw Print Sweatshirt

A cat paw print sweatshirt and a sweet gift for cat moms: a big green paw made of spiraling dots across the chest of a soft fleece crewneck, in oat or flower gray.

Five toe beans, one spiral.

Sunflowers pack their seeds by turning 137.5° between each one — the golden angle — and the spirals you see in the head of the flower fall out of that single rule. We ran the same rule outward from the centre of a paw and only let the dots grow where a pad would be. Everything else stays small. The beans are not drawn; they are the places the spiral was allowed to bloom.

The design

Forest-green dots filling the main pad and four toes, every 21st and 34th dot in rust — two Fibonacci numbers — so the hidden spiral arms show through. A faint field of small sage dots completes the circle. Printed large across the chest; part of Field Equations, No.04.

The fit

Loose crewneck with a soft fleece lining — warm without the weight of a hoodie.

The blank

• 350 g/m² (10.3 oz) fleece-lined fabric
• 42% cotton, 53% polyester, 5% other fibres
• Loose fit, round crew neck
• Sizes S–2XL
• Printed with DTF (direct-to-film) transfer

Giving it as a gift

A cat mom gift that says it with toe beans rather than words. The paw is built from dots arranged like the seeds in a sunflower, so it looks playful from afar and considered up close, and the soft fleece makes it a lounge-day favorite.

• Sizing for someone else: It's a loose crewneck, so their usual size is the right one. Sizes S–2XL. If it doesn't fit, it can come back within 30 days of delivery, unworn, with free return shipping.
• Ordering for Christmas or a birthday: every piece is printed after it is ordered, so count back about three weeks and order before then. The dated delivery estimate under the buy button is the one to go by, and checkout offers express shipping on most garments if you are cutting it close.
