Our wedding party is full but I want to make my two SIL's feel included with the wedding. Although I do not need any special "attending to", I want them to be part of getting ready and I would pay to get their hair and makeup done. Basically I want them to feel part of the day. Is this a bad idea? I read in old posts that special attendant is considered high maintenance and makes people feel bad. What is everyone's thoughts on this?
