I have been doing this for almost 3 years now, I believe. It's such a beautiful technique! You will
easily get into grip with this one. Tom's explanation is flawless.
The only drawback is
that you can't hand out the notes. Though Tom teaches you some methods, it does not appear as clean
as Handout 500 while handing out the notes. But any way, I use Tom's method to hand out the notes
and it works! People have no clue that you have such a mechanism amongst the notes! So no worries.
I still prefer doing this over any other note change. This is that magical! Add to card!
You won't regret it! :)
