这是一款配对纹身图案，一颗心沿波浪形裂缝分成两半，用黑色双层轮廓线画在白纸上。两半相对而立，中间留有空隙，每一半都是干净封闭的形状，边缘有相同的波浪线。你可以更换形状、线条粗细或墨色来重新制作。

A tattoo stencil sheet on a plain pure white ground, showing one heart split down its centre into two separate halves, placed side by side with a clear gap of about 12% of the canvas width between them. Each half is a complete small tattoo on its own: the left half is the left side of the heart, the right half is the right side of the heart. Each half is drawn as a closed shape with one continuous outer contour, so it is a finished design even when worn alone. The cut edge of each half is a gentle matching wave, so the two pieces interlock like puzzle pieces when brought together. Each half is about 30% of the canvas width and sits at the vertical centre, with a wide safe margin on every side. All lines are pure black, a single uniform weight of medium-thin stroke, with smooth round line ends and no tapering. Use no shading, no fill, no hatching, no dots, no gradients and no texture. Inside each half, one slim inner contour line follows the outer edge at an even distance, so the halves read as hearts but stay simple and easy to trace. Keep generous open space inside the shapes and between the lines so nothing can blur together once the lines spread on skin. There is no text, no lettering and no extra symbols. The light is flat and even, with no shadows, no paper texture and no mockup of a wrist. The finished sheet should look like a clean, precise artist reference that two people can show together.
