The curves of slepcat's design are a great idea, but I wanted to use heavier paper than the slots accommodated, and I wished the paper wouldn't come out of the slots so easily. I also wanted a sweep that could stand on its own with more stability.
Although not as elegant as the original, the stand in this design holds thin paper well and also allows for thicker sheets. The rear post helps support a higher background, and there is a plate behind the sweep that can be weighted for added stability.
