glad you're learning some stuff, brostholder. I am too. L and L - I had someone do the window film. I heard from my handyman, who changed out the pantry door and helped with the closets, that it was harder than it looked.
He did his and his son's house, (remember - he's also handy) and said it was not all that easy. You can buy the stuff at Lowe's or Home Depot and do it yourself, but I think most of us would be doing it 2 or 3 times. Some things are worth paying for, IMO. And I'm pretty frugal (my children would say that is a real understatement).
My next project will likely be a rainbarrel in the out of sight corner of my CYV backyard, hooked up to a soaker hose for some of the backyard landscape beds (which aren't all there yet). I put one in our Ohio backyard this spring and love it, love it, love it. I feel so green when I look at it
