In my workshop, it's waste hunting and therefore nothing is lost! Scraps and “failures” of screen printing become dry hot water bottles in mini format. These mini-hot water bottles are multi-purpose: safe in your pocket to warm your hands, to warm a part of your body, on your stomach to soothe colic, in application to relieve your breasts during breastfeeding, in cool compress on your eyes or on a blow… It's up to you to choose the best way to use it. Easy to use: they can be heated in the microwave or oven or placed on a radiator**. Conversely, they cool in the refrigerator or freezer. Random patterns.
