Appliqué
Appliqué or applied work is a method of applying one fabric to base fabric, which is applied using various stitch techniques.
There are two basic types, onlay and inlay. Onlay appliqué has many variations, but its basic form is applying a motif or shape onto a background fabric, which is then stitched either decoratively or blindly. Inlay appliqué consists of two fabrics contrasting in colour; the exact same shape is cut from both, and then swapped and laid into the other like a jigsaw.
