Hi, we're Myna Happy.

We make coloring books for kids who are just learning to hold a crayon, and for grown-ups who want something calm to do with their hands in the evening.

Every page follows one rule: one big picture, thick lines, big open shapes. No tiny details, no busy backgrounds. A three-year-old can finish a page and feel proud of it; a grandparent can color the same page without squinting.

Our books live on Amazon as paperbacks. The same pictures are here as printable packs — PDFs you download once and print whenever a little artist wants a do-over.

Meet the cast: Pip, Bo, Fern, Bell, Mochi and Otto from the winter animals; Rex, Tri, Stego, Bronty and Ptera from the Christmas dinosaurs. They show up across our books, so the characters kids love keep coming back.

• US Letter PDFs, one picture per page
• Paperbacks printed single-sided by Amazon
