Frosted Matt No. 40 Sample Range For sampling ideal colour combinations. The Frosted Matt range includes one 1,000 m MSC spool of each of the 201 colours. The colour effect of a full MSC bobbin allows for a much better colour selection than the small swatches in the colour chart! As each colour can be viewed separately and in every possible combination with other, freely chosen colours, it is also easy to match the colour to the base fabric or the item to be embroidered.
