My underquilt design is slowly getting there... so bear with me for a few more questions and I'll have a prototype to show in the New Year (yes, giving myself 365 days of wriggle room, he he).
When starting out browsing here and on Youtube to get a feel for how underquilts are made I came across a video where the maker put some sort of elastic band (I think it might be called "braid?") into the top-shell of the underquilt. The idea was that it would make the underquilt snug up better to the hammock. Sounds like a sound concept to me.
Unfortunately, I can't find that video any more, and I don't think it had much in the comments as far as the actual experience goes anyways.
So: Anybody tried this here? Does it work? Or why wouldn't it?
Edit: an idea I just had was, would it make sense to have the continuous channel along the underquilt's sides open at a few points and attach shock cord there which could go "across" the underquilt to keep it up? That way the elastic part of the design could be adjusted to be more or less tight... Just thinking.
