Window frames and tar paper

We are really getting down to business on the east side. Decided to build some new frames for the two sliding windows. Under the window wrap, there was lousy dry rotted brick molding that didn't match anything else. My neighbor Jerry designed new window frames out of 1x4s. We kept the original window sill. The beautiful cedar we used should last a long time. Almost a shame to paint them! Also continuing to tear off old siding as high as the windows, and installing new tar paper as we go. I learned that tar paper buckles in the heat of the day, and smoothes out as it gets cooler.
