DIY Carseat Cover

My friend circle has had a baby explosion in the last year (10+ babies born and counting!).  I've become a self-proclaimed baby shower expert, and enjoyed making personalized gifts for each baby.  I've made this type of cover a few times now, but this is the first time I've added a trim.  It wasn't intentional, to be honest, but after not cutting the top material correctly, I had to add material to the bottom.  I followed the tutorial here.  You can do it!  Super easy even for the beginner seamstress.
