Math Rebel Trigonometry Skirt
The trigonometry fabric is knit, so I stretched it slightly along the bottom edge and tightened it a tad at the upper edge to accommodate the a-line shape. I finished the hem with bias tape.
The skirt itself is a smokey gray cotton. The trig fabric is a faded black, so the two together work nicely. I added a little pocket with the sine graph, which is convenient for holding mechanical pencils and other such mathematical things.
Yes, it's nerdy...but being a math teacher, it is how I roll!
