Clover Sashiko Needles are great! We use these sharp pointed needles for sashiko stitching, big-stitch quilting, and mending - and yes, they are strong enough to go through all those layers of denim! They are made from temepered steel, so are harder to bend or break and they are nickel plated so they glide through fabric smoothly. Because they have a unique elliptical eye design they are also easier to thread.
