Cellular & circular stitching

I found this great picture of some plant cellular structure on the web

So I thought I'd try and stich one up myself.

This is what I ended up with after about an hour of work. The circle is only about 18" around.

And here is a rusted, painted, and quilted thing that started out as a rusting technique presented in a class at the Sawtooth Center last month. I quilted it Sunday night, and might add some beads. Both make me think of spring, maybe the recent warm-up here is influencing me.
