First time splicing in a little while; I'm making whoopie slings out of 7/64 amsteel, and I'm not entirely sure on a couple little things. Been searching for half an hour or so, figured it was about time to tap the collective wisdom of the forums

1) Is it necessary to stitch the buries in place? I have neither needle nor appropriate thread for that, so it'd be nice if I could avoid that somehow.

2) How close together should I start the two buries? I set them 12 inches apart on my first attempt, but I feel like putting them as close together as possible would give me a little more flexibility as far as hanging options (up to 12" shorter hang distance).
