The water based guttas have a thick consistancy and are used to create outlines - the Seri technique. The colours are pearlescent. The guttas are directly from the tube and nozzle or from a pipette and gutta nib. They flow readily into the silk fibres forming a barrier to the colour. Setasilk is applied afterwards. All thre guttas can be washed after having been ironed fixed with the exception of the colourless gutta which is designed to wash out leaving a white line on the fabric where it has been applied.
