thank you

My youngest sister will be celebrating her 13th birthday two weeks from now. She's hosting a small party for her close friends. Those have been her friends for around 6 to 8 years already and so she also wants to give them a little something, to serve not only as a remembrance of her birthday but a token of thanks for the years of friendship they shared. It's been ages since I was a teenager and so I've kinda forgotten what 13-year olds like. Hope you guys could help me think of cool thank you tokens for my sis' 13th birthday.

I'm getting married in 6 weeks' time and I'm currently finalizing the not-so-major details of my wedding. On top of my to-do list is to get presents for my 5 bridesmaids. These girls have been a big help during my wedding preparations and I'm sure they're gonna have their hands full during my wedding day itself. For this, I want to give them gifts to show my appreciation. All 5 girls have different personalities, but they are all in their mid-20s. I don't time to buy gifts that suit each of the girl's personality and so I'm more inclined to get them the "safer" gifts.
