Umm...Fail

So I was in the mood to make something small, useful, and cute.  Whenever I'm at Target (love), I always want to buy curling or straightening iron covers.  Let's face it, I'm not a neat organized person, much as I wish I were.  So when I found this pattern, I thought it was perfect!

So I grabbed my adorable purple material....

 And I got to work.  Apparently you should follow the instructions and not make it using leftover yellow felt (I seriously have YARDS of it left after a HS Bowser costume project...ugh) as the batting instead of , well, batting.  My sewing machine and I had a fight.  I brought out the walking foot.  It gurlged at me.  I sewed by twisting the wheel on the side.  The case ended up looking a little strange....

Why does this look wrong?

 I mean, it does fit the curling iron, but I can't help feeling that it looks strange.  Not to self, don't substitute felt for batting again!!
