square plastic in da middle

My 'sewings' 4 this time. It's like another white sleevless shirt I made (I also made one a week ago 2) that I at first didn't know what to do with, but then I thought I wound use something a littel unusual like plastic, and make a square in tha middel with. It's a littel hard to sew the plastic on (since it's plastic and always rip when i pull the thread -.-) But yeah, show you guys when I done :D
