  1. Hello! I just wanted to ask if you ever have any issues with hackers?
    My last blog (wordpress) was hacked and I ended up losing months
    of hard work due to no back up. Do you have any methods to protect against hackers?
  2. This design is incredible! You obviously know how to keep a reader amused.
    Between your wit and your videos, I was almost moved to start my own blog (well, almost…HaHa!) Wonderful job.
    I really enjoyed what you had to say, and more than that, how you presented
    it. Too cool!
    • For a 5:30pm wedding, you want to decorate the MORNING of the wedding, not the night before. The flowers will look horrible. I know this because I talked to our florist about it. We had our wedding at 5:30 and she was there bright and early the morning of our wedding to decorate. It was great. Everything looked wonderful. She did a GREAT job and so, I feel like if she….a professional flo2.st&#8r30;.ichose to do them the morning of, then she’s probably right.
