I have several problems...at least that I am willing to admit on this forum

1. I move around a lot when I sleep.
2. The DIY IX underquilt I made doesn't seal well- likely too big as it has shock cord through grosgrain and it will "ride up" and vent. Was camping this weekend and it was in the mid 30's and I felt cool, not cold.
3. I don't particularly like the feel of the tight shock cord when it does seal.

So that lead me to thinking that one could, perhaps, attach an IX underquilt by Velcro. The seal would be good and it wouldn't move around and need adjusted. Has anyone tried this before? Will the stitching of the Velcro to the hammock weaken the hammock? Any ideas (other than "try it and let us know!" )
