I think that tutorial is enought to explane how to do them. Suprisingly they lasted about a week on ringfinger but on thumb just two days. It looks pretty on fotos but foil is creased which doesn´t do the best final look. Try that, maybe you will do it better than myself.
By the way, do you want this descibe in slovak language, too?
Inak, chcete takýto komentár aj v slovenčine?
