After finishing my pinwheel quilt top I am ready to baste. Basting just holds the top, batting and back together so it doesn't shift while quilting. I know some people use safety pins for this but I've heard it allows too much give. I've never tried it. I also know some people just run quick lines on their sewing machine. I prefer just to hand sew wide stitches across my quilt. My stitches are about 1 inch long and I run a row every six inches or so. It doesn't take very long at all and I know my quilt isn't going anywhere. Also, it is very easy to take out once I am all done quilting.
