Methods of forming garments having one or more stretchable conductive ink patterns. Described herein are method of making garments (including compression garments) having one or more highly stretchable conductive ink pattern formed of a composite of an insulative adhesive, a conductive ink, and an intermediate gradient zone between the adhesive and conductive ink. The conductive ink typically includes between about 40-60% conductive particles, between about 30-50% binder; between about 3-7% solvent; and between about 3-7% thickener. The stretchable conductive ink patterns may be stretched more than twice their length without breaking or rupturing.
