Colcolastic is manufactured using 93% Mercerised Cotton and 7% Lycra. This is the Venne 20/2 mercerised cotton lightly twisted with a fine Lycra thread. The stretch, pleat and bump effects appear when the fabric is washed. The potential for different effects is endless depending on the type of yarn, fibre and structures used. We stock the full colour range on mini spools (150m/165yds). It is also available on 50g mini cones. Please contact us to order and for details of availability and lead time.
