depends on how the church is.
If its a traditional church w/ high ceilings etc...maybe a few flowers will do.
we are putting a few floral arrangements at the end of the pews. the church itself is very ornate already so we are not going to over do it. our church does not allow rose petals or the throwing of anything for that matter.
my church is very simple, cute and small... (only 9 pews down the center isle, so 18 total) so im thinking simple tulle bows or something with our colors, theme, or silk flowers.... i just dont like those gift bow things. i havent a clue what i will decorate the front or the alter with. :(
i tried finding a pic of this next look, but couldnt, so i will describe. if your church has a communion table, then put a white table cloth over it that will go to the floor. put a floral arrangement on both ends of the table and if you plan to do a unity candle or sand ceremony that can be in the center of the table along with maybe a some scattered rose petals. the floral arrangements can be as expesive or cheap as you want. a huge mass of babys breath is beautiful.
I think each church has certain rules so make sure you ask. For example, my friend is getting married in just over a month and her church won't allow real flowers for the flower girl because the petals could get trampled into the aisle and ruin the runner, but they insist on real flowers on the alter, fake is not allowed.
So make sure you check the rules and work within that as to what you like, you don't have to do a lot of decorating if the space is naturally pretty.
I agree with Sammy. Depends on the rules of the church. Some churches do not allow certain things to be done in the church or the church is adorned in a way where it doesn't really need decoration. Check with the church and see what the rules are and go from there!
It depends on the church. My SIL and BIL just put up a few floral pieces and then decorated the reserved rows with a flower or two. It wasn't much but it looked good.
