Ther are usually two cermonies the first is the Kob kru ( laying on of the Ruesii head). Following that i think two days after is the Big festivell that i believe you are talking about. I have been studing Sak Yant ( thai tattooing) for a few years now so if you have some questions just send them to me. I let you know when the Wai kru cermony is on when i find out. And like Richard said dont get it on the day, go a week or so befor
