I did a dry run. It took me 4 tries before I folded it right. The origami fold was the winner! :-D I am not sure that it completely opened, though. I felt around the edges as best I could and it seemed open, and it also had some resistance when I tugged at the stem a bit. I walked around for like 15 minutes, and there was only slight discomfort from the stem, which I intend to cut off after a few more dry runs.
I'm just really excited it was successful. LOL. I swear it was going to be a huge mistake after reading a few peoples' frustrations, but it was great. I just want to practice a few more times before I get my period again, and I want to make sure it is completely open. I have time, though. Then before my period I'll cut off the stem and be good to go!
And it took less than a week to get here. WOW.
