Here are a couple more options. I know you said you didn't want to use bows, but the second picture would go with your romantic book theme. And the third would be a way to dress up the bow. The first pic you could use an inexpensive flower like carnations (they have a bad rap, but they come in a gazillion colors and are inexpensive) to create an inexpensive pew decoration.
WOW that's a lot of pews! I only made 6, but I had probably enough tissue paper and ribbon for about 3-5 more. I'm only having 30 people at the ceremony so I only needed 6, 3 for each side skipping rows. There will be the empty rows towards the back but I'm not worried about that. I think 30 of these pomanders would be a LOT of work, I only made six and I was exhausted. I ended up making about 25 flowers per pomander so that would be hard to do.
Though I have been married for nearly 20 years, I am currently doing wedding decor for new brides. When looking at wedding sites, I came across this blog, and thought I would share a picture of the pew decorations I just came up with and put together for an upcoming wedding I am working on. These pew decorations were very inexpensive (less than $1.50 each in materials) and very simple to put together (about 10 minutes each plus time for paint to dry).
Just now finding this forum but am excited to offer 25 beautiful ideas. My company held the World's First Pew Decorating Competition this past September and saw some truly creative and inspiring decorations. From Simple to Crazy Busy - there was a lot of beauty there that night!
