I had a need for an eighth drip circuit, which I had to run behind the make-shift paver pad I installed for my pool junk boxes, way back when. This inspired me to pull up all the pavers and rebuild that pad, as it was never done well, and was never flat and level, and that caused the lids of the boxes to seat crookedly, which has always bugged me. I installed a frame; left, back and right; and then some sand and leveled it as best I could, then put the pavers back and cut some new ones to fill in some new gaps. It came out OK.
Note the two scraps in the middle. Normally I wouldn't do something like that, but the two scraps were leftovers from the other cuts, and didn't require even a shave. They just dropped right in. Considering I'll never see them again, it wasn't worth the effort and waste of cutting another whole paver just to get rid of that seam.
PRO TIP: This obviously isn't "patio quality" work, but when you need that, the trick is, before showing the end result to anyone,
cover it with furniture! 
Ta, da:
All flat and level, and the lids now close perfectly! (I'll power-wash the whole pad in a few weeks.)
I panicked in the middle of the job, realizing that the new pad must be somehow smaller than the original, so I measured the boxes and was 4" short. Ugh, now what?! I really hate when stuff like that happens, but... I measured wrong! And as you can see, I couldn't have ended up with a better fit. I did the whole job with scraps of boards and pavers I had leftover from other jobs. Yes, I'm a pack-rat, but it often pays off. For those that might be worried, I am
not legally a hoarder, because I have less than 20 magazines in my entire house, and they aren't in a stack!
So not only did I use up some old junk laying around, I used up nearly all of each piece of junk! This is what was leftover from the leftovers. Something comforting about that!
It was tough, but yes, I threw these scraps in the garbage. Gotta draw the line somewhere.
Tomorrow I'll run the rest of the new drip line...
