Large piece of paper (or a few letter sized taped together)
About 1 yard of fabric (depending on how large the skirt will be)
To make the pattern, go to this tutorial over at Made. Keep in mind how long the doily is and whether you want the skirt to extend past the bottom, just reach it or not hit the hem at all (like I did). Once you have the pattern drawn up, cut it from your fabric as described in the tutorial, then create a rolled hem along the bottom edge of your fabric.
