This tool is awesome for preparing Applique or English Paper Piecing with starch and freezer paper. It saves your fingertip and fingernail from a hot iron. It becomes a natural extension of your finger, helping you handle your pieces. It is adjustable to fit your finger – a little Hexie Helper! It also works great to offer finger protection when using sewing machinery by keeping your fingertip away from moving needles / parts. This is a notion you can not do without!
