I agree, John. The height of the panels is more important than the width. When I made mine, I made them 48" wide and 72" high. That way I used all the 10' of PVC and had little waste. I used a hacksaw. PVC is very easy to cut and sand (I sanded the cut edges to remove any sharp points). Before I made mine, I went outside and measured the height it would take to block the light. That's how I came up with 6' high. Here's a pic of what I ended up with.
