Finally, a Japanese line you can actually buy. Yumiko Sekine's Fog Linen is a rigorously rustic line of natural-colored linens: sheets, dishtowels, aprons. Design Within Reach carries a wide selection; Selvedge stocks her bed and kitchen linens; and The Gardener in Berkeley carries her dishtowels and napkins.
