When should I use speciality backings?

Speciality backings such as poly mesh and nylon mesh are also options. While they may not be as stable as traditional cut-aways, they are much less visible through lighter weight garments. They also tend to be softer than other backings. Water soluble backing is also available for jobs that require that no backing be left after the completion of the embroidery. Be aware that this would require a fairly stable garment as the backing will be dissolved completely and offer no support once the garment has been laundered.
