A whole shirt dress couldn’t satisfy my craving for polka dot clothing, so my current project is a red circle skirt with little white pin dots. Fabric is basic quilting cotton from Joann’s, which I got for about $3 a yard, and which has shown an unfortunate tendency to form wrinkles that refuse to be ironed.
I made the pattern out of newspaper (I find the classified section works well for this), and used the equation for a circle to figure out what radius I needed to get a waistband of the appropriate size. This is the kind of math that even poli sci majors can handle, so imagine my surprise when I finished cutting and found that the waist was about 3 inches too wide. Still not sure exactly how it happened, but I’ll take that into account next time. I ended up inserting a back seam with a zipper to take up the slack, which saved me the horror of trying to insert an invisible zipper next to pockets.
A picture of the work in progress:
Blurry, I know, but you get the idea.
