They say patience is a virtue, but for some artists it’s a necessity. Emi Nakajima’s detailed ink drawings of famous architectural sites, which recently appeared on My Modern Met, typically take about a week to complete. However, her most ambitious undertaking yet—a rendering of Thailand’s Wat Rong Khun (White Temple)—was a five-month endeavor.

The Japanese-Thai artist told Mental Floss that the White Temple was particularly difficult to draw. She typically uses A3-sized paper (11.7 by 16.5 inches) for her projects, but she decided to draw the ornate temple on a much larger scale. The paper covered her entire desk—and getting each arch and spiral just right was no small feat. She took her time on the details, chipping away at the drawing after returning home from her day job as an administrative officer in Thailand.

She’s amassed nearly 39,000 followers on Instagram, where she documents the progression of her projects from start to completion. Although her prints aren’t available for purchase online, she does sell her drawings locally.

European architecture features prominently in her work, with past projects including drawings of London’s Big Ben, Barcelona’s Sagrada Família basilica, and France’s Gothic churches. She occasionally branches out from architecture, creating 3D images of food and drawings of superheroes, movie characters, and animals.
