I bought these needles because I needed a thin needle that would not show holes in my seams. I make men's neckties, and hand sew the back seam. Being a man, most needles that would fit comfortably in my hand were either too big and left holes in the fabric, or the eyes were so small, I couldn't thread the needle. Then I was reading online about different needles for different projects and fabric. After much research, I decided to give the milliner number 10 a try. It has a large eye, and although still a bit small, I can at least thread it with little difficulty. These needles are light weight and feel good in my hand and are easy to use. I definitely recommend them.
