A template sheet is provided for use in the application of a medical grade adhesive to the skin of a user. In one preferred embodiment, the template is fabricated of a flexible plastic material having one or more openings in the sheet and marker openings are provided about the periphery of the one or more openings and through which the skin can be marked with a marking implement. By use of such markers on the skin, the template can be removed after placing the markings on the skin so that adhesive can be applied to the skin within the marked area without need for the template to remain in place during adhesive application. Alternatively, the template may be employed as a mask and the skin adhesive may be applied to the skin while the template is appropriately positioned on the skin of the user. The template may optionally include a strap or belt by which the template can be held in place on a users body while adhesive is being applied and without requiring the use of the users hand to hold the template in place. As a further alternative, the template sheet can have adhesive on one or more defined areas of the sheet. After adherence of the adhesive to the skin of a user, the template sheet can be removed to leave the adhesive in place.
