Hi, This is Cuchy. I made this tutorial for Inspirational tips, techniques and tutorial blog.
I'm glad you like it and thanks for linking to my blog.
I don't understand a word of your language, but according to Google translator, you're asking if the tape will be enough sticky after soaking with the water and removed the paper.
Well, it depends how heavy your tape is. But you can always use glossy accents or even staples to attached it to the cardstock.
Hope this helps. If you want to clarify anything of the tutorial you're invited to visit me at http://la-almohada.blogspot.com
