How to Curve Needles
Curved needles work very well when sewing a coptic stitch. It allows the stitching to be tight. The curve allows you to "hook" around as you are sewing. You can also make your own curved needles out of straight ones.
I like to use darning needles in size 1 to make my curved needles. They have a slightly larger eye than most purchased curved needles which allows me to use thicker threads when sewing. Thicker threads work with thicker papers and give a more pronounced stitch.
