The small practical Prym pattern weights are very useful aids and facilitate the work of cutting patterns and materials, also on the cutting mat. The four handy fabric bags, filled with small metal balls, keep thin pattern paper and fine fabrics reliably in position, thereby enabling precise cutting. With its soft surface, it is gentle on the material and leaves no pressure marks. The fixing weights are a helpful aid especially for fabrics on which pins leave holes, for example oil cloth of soft shell fabrics.
