Can I shim this to fix or

First of all, I've never hung a door before, so forgive me of any blatant stupidity. I'm building a small cottage in the back of my property. I built it with 2x6 walls. It's all framed, sheathed, roofed. I went and bought a 36" prehung door from Lowes, then realized that the frame it is hung in is sized for 2x4 walls. Does it matter? It looks like the inside of the frame (and hence, the barrels of the hinges) will be about 1" shy of the face of the inside wall. To me, this seems like a problem. Is the door going to bind against the corner of the opening every time it's opened? Are there specially prehung doors for 2x6 walls? Eventually, I will also get to this same question for some in-swing french doors, where I imagine the answer (either way) will be the same. Thanks for any help!!

I've been rescreeing my old windows with the plastic /fiberglass screen. Two questions: 1. What's the best way to end up with a taut screen without ripping the material. I've been using clamps. I find it some what of a pain because I find myself trying to stop the screen from bunching/wrinkling & sometimes I finish a screen only to see it tear at the spline point a few days later. Of about 16 screens I've done I'll probably have to redo about 4. Any hints to make it easier? 2. The screen frames are pretty beat up with grime & some pitting. Structural intact. I've been using steel wool & a hose to try to clean them up before rescreening but it works so-so at best & requires a fair amount of time & elbow grease. On a few I tried sanding them or even using my grinder but neither does a great job. Any tricks or recommendations? Thanks
