I am nearing the end of my first baby blanket for my boss! By the end it will be a square with the white section being the same width as the blue sections. I want to put a little border on it to tidy up the edges. What color of the 3 should I use and what stitch? (No shells, he specifically said he didn't like them when requesting the blanket.) Thanks so much!!

I am replacing my p trap for the first time and it seems I need to cut the old run out and completely replace it. I am concerned about the piece going through my wall. How do I replace it? I feel like I can't cut it on either side of the coupling because I wouldn't have enough pipe to bottom out in the new coupling. The picture shows what I wanted to do with the first half and where I'm confused on the second one. I appreciate any help you can offer!
