This is a very artsy stencil design that will make a unique baby onesie or t-shirt. I wanted something that was very unusual but still playful, so I hand drew this design and then converted it into a stencil digitally. I separated a few of the shapes and colored them grey, so you could use that as a suggestion for making a second color stencil. You can also paint the whole thing as a gradient (see my tutorial for gradient stenciling), or in any creative way you see fit.
This design results in a really fun and hand-made look. You can also block off areas of the design and use just a few elements on baby’s sleeves or infant pants etc. Feel free to use it as inspiration to decorate anything else you can think of.
