Modern Chair Tone Down

I found two really cool red modern chairs on CL.  Here they are,

So here is the plan.  I bought this fabric to make slip covers for them.

Stay tuned for the finished results.  I am going to attempt to explain how I make the slip covers.  This should be interesting lol.  I don't know how to sew.  Well, I guess I should say I am a self taught sewer and there was NO reading a books involved. ; )
