Honestly, my experience with box pleating has been a rough ride. During my initial days of origami, I was so attracted to box pleating that I decided to take out two hours every day and practice this technique but little did I know that two hours were not enough to get the design right.

Those two hours slowly converted into three, then four. The very first model I created with box pleating was a flower vase, it took me nearly a month to complete the design, with so many unexpected errors every now and then and multiple redo's due to these errors.

LillyJuan, what I can suggest to you is to start meditating as box pleating will take a lot of energy and a huge amount of patience from your side. You have just experimented this technique on the skirt folds and even the gift box (as suggested by Ryan) is a pretty easy task. However, when it comes to complicated designs, you will need a lot of strength and patience. I'm not trying to scare you, just warning you.
