The Prym circle cutter with rotary cutter blade is revealed in the best OLFA quality; it makes it easy to cut fabric circles of radius of 4 to 22 cm. The circle cutter functions like a set of dividers and is the ideal tool for patchwork, quilting and sewing. To make appliqués, fabric yo-yos, bulls eyes or compass quilts: Simply place the fabric on the cutting mat, set the radius size to the circle size required, remove the protective sleeve and release the blade. The use of Prym fixing weights prevents heavy fabrics slipping. The circle cutter handle is fitted with a ratchet function, which allows it to move flexibly around the circle.
