Appliqué and Patch Work are 2 techniques that are famous all over the world for enhancement of fabrics and products. These 2 happen to be my favorite too as they generate a lot of surface interest and novelty by means of ornamentation.
In earlier days, geometric motifs were used to build the patterns for the 2 of these and these techniques were considered to be a good form of creative past time. Today, we look up to these techniques to add essence and focus to a particular look, be it for fashion, home or lifestyle products. Moreover, designers these days are trying out a lot of unusual shapes in appliqué and a lot of different textures for patch work.
Patch work is a form of fabric craft or needle work in which fabrics are sewn together carefully without any puckering to make a larger design or fabric. Whereas, appliqué is a craft or needle work in which a cut motif/pattern is sewn over the base fabric in order to decorate it. However, both the techniques are even crafted with machine these days.
Here are a few pictures to demonstrate how patch work and appliqué look like.
