You can create some papers and elements for baby pages with circles and a few other simple shapes.
Let's begin with the simplest buggy. I created this in Microsoft Digital Image Pro Suite 2006. I inserted a circle shape, cut it in half, then in quarters using the half as the bottom and the quarter as the hood. I added smaller circles for the wheels and the tiny bit cut off the bottom of the circles to add as a handle to the side. The other shape I used as a handle. This can be enhanced and made into a fancier, more complex design.
