I often adopt a mixed media approach and interchange pens and pencils for found materials, as well as frequently incorporating photocopied segments and mark making.
For my illustration business Peach Panda Studio, I rely on digital illustration to translate into my product ranges. Most often I use an iPad Pro and ProCreate software, but I usually start with a small sketchbook and translate the designs digitally later.
Using my sewing machine, I am able to create freehand stitched images without templates or digital software. Drawing on the sewing machine is one of my favourite methods of drawing and it's where most of the products in my shop start off.
