Need suggestions for make-up, jadai alangaram for seemantham (baby shower)

hi,
I am 4 months pregnant now, and next month i am going to have seemantham.
seemantham is at my in laws place.It is a remote village and we cannot find ready made pula jadas.
so, iam planning to have readymade jadai or prepare one my self using motifs beads pearls flowers etc...
so,i need some suggestions regarding this.how to make,where to buy etc wth pictures if possible..,
I have heard that any chemical facials etc can hurt my unborn baby.
is that true?
pls suggest some facials and make up products or natural ideas to glow on the day of my seemantham. my skin is a bit oily and present have small pimple marks how to get rid of them.
thanks in advance
