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.

The method of claim 1, wherein the layer of conductive ink comprises between about 40-60% conductive particles, between about 30-50% binder; between about 3-7% solvent; and between about 3-7% thickener. 3. The method of claim 1, further comprising peeling the transfer substrate off of the conductive ink pattern. 4. The method of claim 1, further comprising attaching a conductive thread to the compression fabric, wherein one end of the conductive thread is electrically connected to the conductive ink pattern. 5. The method of claim 1, wherein the transfer substrate further comprises a conductive thread in electrical communication with the conductive ink pattern. 6. The method of claim 1, wherein transferring comprises applying heat to transfer the conductive ink pattern. 7. The method of claim 1, wherein transferring comprises applying heat from about 130° C. to about 300° C. to transfer the conductive ink pattern to the compression fabric. 8.
