My first biscornu

Well... This is my first attempt in making a pillow called bis-cor-nu (YAY, I finally typed it right! )
And I just couldn't find a name for this artwork. Silly me. Of course, I could just name it after the pattern I used, but here is the pattern that I made by myself!
Yeah, I'm surprised, too
I was making the pattern in my textbook during Geometry lesson! (Oh, no! Don't tell it to our teacher, or I'm dead ) So count this as an interpretation of my tired mathematical mind
Technically, it cost me nothing at all - I used the 5 squares per cm Aida left from my Lady Butterfly project and lots of unnamed threads left from the kits I had stitched before
And I also used beads and these big shiny star-shaped buttons!

Well, and I think that it turned out fine... For the first time, of course
*P.S. And that is also the first time I sewed something PROPERLY! *

Edit: Oops. I forgot to write that it's my entry for the challenge in the #stitchingpirates group! Silly me. It's the first one I'm taking part in ever, so... Good luck!
