That is going to be tough… hmmm.. anyone willing to help?! I am sorry, but I am of no help as I will be getting married in Germany according to the German tradition. Why do you have to do the mehndi and wedding ceremony in Germany? I guess it would be wayyyyy cheaper in Pakistan and less of a hassle… Maybe your fiance’s family can help you… I assume they must be staying in Germany…
Anyways, best of luck!!!
