I have a feeling that brides often don't have the in-laws in the wedding party. When I married almost 27 years ago, I didn't have anyone from my dhs family as bridesmaids. Mostly because I really didn't know them that well at that time. If I could go back and do it all over again...I would have all three of my sister in laws standing right there beside me. I consider all three of them my best friends. But, like I said....back then I didn't know them. I had spend very little time with any of them and I wasn't comfortable having them in the wedding party. Now...many, many years later and much wiser....I realize how lucky I am to have such great sister-in-laws. To this day....they have never mentioned the fact that they were not in our wedding. I ended up being a part of two of their weddings, but it was years after our wedding and by then we had become very good friends. I guess I feel that its important that you have people that know you well, and are thrilled to see you happy be a part of your wedding, and the fact that you will be sister-in-laws doesn't mean that you will be *friends*, although I would hope that would be the final outcome...
