DIY bridesmaid cards

So I wanted a memorable way to ask my 5 bridesmaids to be in my wedding. I plan on doing all the paper goods myself so I thought why not make cards for them! It was really easy to do, all I did was get navy cardstock in size 8 1/2 x 11 (JoAnns, on sale 5 for $1) , silver gel pen, scrapbook stickers ('Beautiful Bridesmaids', $1.74 at Target). I cut the paper in half width-wise to get 2 cards per sheet, and scored it down the middle. I placed the lettering along the bottom first, doing the bridesmaid first. After laying down the stickers, I wrote with the gel pen on the outside and inside. Once each was done, I placed in a hardcover book to make it lay flat. I also bought a pack of size A2 envelopes for them.
