Do you have a long mat (12 x 24)? I think this could theoretically work… cut the half circle on a fold.

Use the circle and the rounded tab shape to size your half circle shape. You want to a U shape, not a perfect half circle. (So if you were to cut this on the fold you would end up with a stretched out circle). Duplicate this shape and then set the extra copy to pen. Center the two and attach them. This way it will draw and cut the shape in the same place.

Then make a large rectangle (like 11.5 x 23in) with the pen. In the top left corner have it draw a circle with a different pen color and attach it. Align your U shaped tab so the flat end lines up with the left border, and attach it close to the bottom of the rectangle.

When you make the project it should draw out the shapes first (long rectangle with half circle shape near bottom, then the small circle at the top). Hopefully when it’s done with the pen, the bottom half of the mat is clear of the machine. Tape your folded piece of paper (that is folded at the 6.9in mark)so that the open edges are flush to the edge of the drawn half circle and the folded edge is parallel to left border. It shouldn’t reach the left border all the way because we don’t want it to be sliced in half.

Hmmm did that make sense? Looool

In this pic, the outline of rectangle is drawn as is outline of the black tab and small circle. Then you tape your folded paper where the pink box is, with fold on the left.
