Our favourite brush for calligraphic marking-making in watercolour, gouache, ink and fluid acrylics, has to be this Synthetic Quill brush. The series 488 utilizes the daVinci CosmoTop Spin blend of 5 diameters of synthetic hair mounted in a clear plastic ferrule replicating a goose quill. Brass wire is hand tied fastening the hair bundle and clear varnished wood handle to the ‘quill’. The resulting brush has the look of a traditional quill. The synthetic has far superior snap and point, but less water carrying capacity of blue squirrel. The CosmoTop Spin mix is a delight to paint with and is visually stunning in the traditional quill presentation.
