This Clamshell template set (2 templates) is ideal in working with large print fabrics. You may use the template to fussy-cut the fabric to get the exact cut you want!Our patent-pending Slit 'N SewTM method represents a truly revolutionary improvement by allowing curved piecing to be done quickly and easily each and every time! Using the CutRiteTM Slit 'N Sew templates, simply use a rotary cutter to make small cuts that are precisely located on the templates. Then proceeding a slit at a time, line up the next slit from each piece that is being pieced together and sew to that slit. The result? A perfect curved piecing job in no time!- No tedious and time-consuming pinning!- No paper piecing!- May be performed by quilters of all skill and experience levels.- Works for non-curved shapes such as diamonds and tumblers - just match the slits and the points line up automatically!- Ideally sized to work with standard pre-cuts, such as 5" and 10" squares, or use with other fabric that you have.- Easy to see fluorescent green acrylic color!- Includes CutRiteTM HandiGrabber material to keep template securely in place.
