I have some of those Clover Wonder Clips (which really are wonderful!). I'll bet they would work great to hold the binding just right until the glue dries. I'm going to try glue basting as well on my next Project Linus quilt after the holidays.
As far as the no iron binding... don't think I'll bother with that. I'm really happy with how my binding turns out and I'd rather iron it and have a nice clean edge to attach to the quilt instead of having to pin it or futz around with it. I try to avoid pinning!
