Sorry I've been MIA lately... now that we are winding down into the last month before the wedding, I really don't have as much time to be on the knot as I did before.

( I hope everyone's planning is going good!

) I'll have to catch up on the posts later in the day.
I do have two questions for you guys though...
1. I am extremely frustrated with the post office, I've had 5 people so far tell me they never got their wedding invitation, and I'm wondering how many other people didn't get theirs.

( I don't know WHY that many of them could have gotten lost... and I'm wondering should I call the people that I haven't heard from to make sure they even got theirs, or just let it go?
I have extra invites, but I only have 10 extra, so after I made 5 more, that leaves me with 5 left. I don't want to have to buy more supplies for lost invitations either, and at this point I think it would get to them too late anyway. What do you guys think?
2. I hand painted wine glasses for my bridesmaids as part of their gift, well I decided last week that I wanted to do the same for my other friends who are helping with the wedding but not in the bridal party. My sister is also helping with the wedding, so she's getting one. FI's sister hasn't helped with the wedding, and she hasn't mentioned helping the day of the wedding either... so I'm wondering if I should make her one or not.
She and I haven't had the best relationship throughout my relationship with her brother and things are better now, so I wouldn't want any drama to start if she or FMIL feel like I left her out... but then again, this gift is a thank you to our friends for helping me with the wedding, and she's not doing that.
It literally takes 10 mins to paint a wine glass, so it wouldn't be a big deal to make her one, I just don't want everyone else thinking, why is she getting something, she didn't help... Am I thinking too much into this?
