CALLA is a double width plain curtain fabric made of a wool and alpaca blend which creates structure and texture whilst having a soft handle. The characteristic feature of this fabric is the weft with a thick, mottled wool yarn in large floats, which contrasts with the transparent warp. The weaving process creates two different sides, the front which consists mainly of the floating wool wefts, whilst the back has the appearance of a fine organza ground. CALLA is available in four neutral tones.
