5. Heart stencil
Photo: pinterest.comHeart cutout stencils and templates can help you make lots of paper, cardboard or fabric hearts, and also to create different heart patterns and designs using paint or markers. Printable ones can be found online, but basically when you cut a heart shape out of cardboard just once, you get two useful tools: one to be traced around, or covered with paint to produce prints, and another to paint inside the cutout area to get a perfect heart anywhere you wish.
Both can be used to decorate mirrors (easy, colorful and washable), cards, posters, homemade gift wrap or gift boxes, but if you have textile markers or paints (easily found online and in craft stores), you might crown yourself a DIY king or queen.
