I've just put this piece of boro on the website. It's a large, very old futon cover that's been opened out lengthwise. The main panel is a piece of tsutsugaki. Tsutsugaki is created by drawing a rice-paste resist design on to the fabric with a tsutsu (a cone a bit like an icing bag). It's then dyed in indigo and sometimes other colours are added. The back of the fabric has been extensively patched with plain, striped and checked indigo - which of course is the bit that we boro fans love! It dates from late 19th - early 20th century. The tsutsugaki panel would originally have been an expensive piece, not something peasant farmers or workers could have bought, so there will have been an interesting story as to how to came to be in such a humble state.
