Black fabric, I used 1 yard of black Kona cotton
Batting, the thin stuff
First determine how large you would like your individual spider webs to be and pick a bowl about that size. THEN pick a larger bowl then the one you are holding and put the smaller one away. Trust me. You lose a lot of bulk when you cut out the spider web shape, so you want to start bigger then you think you'll need. Trace around the outside of the bowl on paper.
Now to make the spines. Start in the center and sew out towards a point, then simply pivot your machine 180 degrees and sew back down that same line to the center (shown below if you can see it, it was dark that day and I forget I can use flash). Continue for each of your points. Don't worry if they don't line up perfectly, it just adds to your spider webby feel.
