All you need is:
If you want to get all fancy shmancy, you might want to take off the old seat cover, but I was honestly too lazy. Also, recruit a helper. My sister in law happened to be over when I did this, and she saved me from making it look pretty bad, sometimes I have no patience when it comes to DIY projects. The hardest part is just making sure the fabric lays right on the chair and stapling it on right the first time. If you try and be patient and go a little staple gun crazy, it's not that bad and you end up with a pretty cute, chair seat in the fabric of your choice! I love my black and white stripes!
