What is the best birthday gift for my sister.?

Since I don't see many details about your sister (where she lives, what are her likes / dislikes, etc.), I am responding to you as an elder sister myself. My birthday was Sunday and my sister lives 3 hours away so we couldn't spend the day together. I asked her for framed photographs that she had taken of family and her local scenery for my new house. It helps me feel close to her and adds something special to my home. The best presents don't always have to cost money. If you feel you must buy her something, there are digital photo frames that hold tons of pictures and cost around $100.

Well I think birthstone pieces are always very special. Even a picky sister would appreciate it. Does she wear jewelry?

Hi sanju21, Happy birthday to your sister, I just had mine on the 13th. Whenever I have to buy a present for someone that is very picky I usually end up either a) putting money into a birthday card. b) Buying them a gift certificate to their favorite store. Hopefully my suggestions help a little. Take care.
