My other question is how can I insert the cup through such a tiny hole? I tried the diamond, origami, and the c (c is too big) fold, but I wasn't successful. Sometimes it hurts when I slowly push it. Maybe it's the way I insert it? How do you guys insert it? What general direction do you insert your cup? Also I can hardly hold the cup because it would unfurl from the fold right when I insert the tip of the cup. ._. Any advice?
In short, what's the tiniest, thinnest fold? In what direction do you insert it? How do you fit a lunette through such a tiny opening? Thank you! :)
