well, I imagine that if you're not making them all the time, you would probably need a refresher. You probably haven't forgotten completely though. I used to make lots of paper lotus (lotuses?), but stopped after a year or so. I could probably still make them, but I'd need to look it up again.
This is awesome!! I love the hearts. I've done plain hearts and the one with wings before, but I am intrigued by the outer ones, since I've done the design before for a box, but not on a flat surface. I'll go to the Youtube of how (appreciation for including it!) if I can't figure it out... hrmmm **starts to troubleshoot**
