SohIm was founded by two designers - Patricia the craft lady and Choi, a leisure illustrator. The collaboration came about when Choi jammed at Pat's craft room and was overwhelmed by Pat's crafts - bags, designers' fabrics, clothes and so on. While Choi had a series of illustrations drawn over the years, she thought it was a good idea to have her illustrations printed on fabric that could make into crafts of all sorts. Three months later, SohIm launched the first granny bag series - Granny Crafts.
SohIm's illustrations are printed using large format digital textile printers that show greater design detail than screen printing. Unlike conventional textile manufacturing, digital printing entails very little waste of fabric, ink, water or electricity. The illustrations are printed on natural fiber textiles using eco-friendly and water-based pigment inks. No additional chemicals are used in the printing or preparation process. The fabric can also be machine washed, either warm or cool using phosphate-free detergent. To enhance the finishing further, the exterior fabrics are mostly designers' fabric, such as Amy Butler, Alexander Henry, Patricia Bravo and so on. Every piece is one of a kind and is hand crafted by the designers.
Choi's illustrations unfold stories of her sentiments towards people living at the periphery in the contemporary society.
