This is one of Steve Goods patterns.
I made one and found pages didn't line up as expected.
So made the next one and added 3/8 inch to length and 1/4 inch to side.
Also waited til I had the paper before I drilled holes for the rings.
That also lines paper up better.The paper and rings,I got at staples as did Steve.
100 sheets for $4 and 16 rings for$4.
Wood is 1/4 inch oak ply for both front and back covers.
I glued blue poster card on inside cover.
Three photos here..you can see the difference in Cathy one which was the first
one I made.
