Just a note about the pipe and pipe clamps Beth
Pickup some BLACK pipe ( 1/2" pipe will do the trick ) , I don't how many pair you got but if you buy pipe that is 4ft.6ft,8ft,10ft,12ft long and then take your hack saw/pipe cutter and cut it in 1/2 you will have a pair of each size...most of the time it's threaded on both ends,, from HD,Lowes,Ace Hardware, etc.
Then b/4 you slide and screw the clamps in place make some blocks to fit the clamps, this will keep the nasty marks off the wood and you can make the blocks just a bit taller than the clamps and this will hold the clamps up off the work bench and they will stand up so you can crank them up will out removing skin from your kuckles,you can also buy the push on plastic type but you can make your own quick and easy with some scrap 2 x 4 stock...
( block=2 x 4 x 6" long with a hole on one end and use your router to put in a slot b/4 you cut them to size..so they side over the clamps/pipe..
Plus if you hang them over a window it will help keep the bad guys out
But you still get the light from the outside..
