Non-penetrating way to attach Twine
The cool part about Twine is the device is a sensor itself (vibration, etc). That implies attachment to something that moves (ie a door). I'd like to do that but I don't want to penetrate my door with a screw. Anyone have success attaching with something non-penetrating that is strong but doesn't impair the surface/finish of where its attached?
Then, the plastic holder could be fastened to whatever and Twine could be easily removable. I'm sure something could be added so that Twine would not fall out if it were tipped.
