I had originally wanted white heart shaped floating candles for my centerpieces. Then my fiance saw a picture with fish bowls as centerpieces, so now I am breeding and raising fish (which I had done in high school, so I'm no stranger to it) for the wedding! My mother is also making table runners with gorgeous embroidery on them (lucky for us she has an embroidery machine).

Flowers used for the wedding ceremony can be used also for the center pieces.

I used clear labels to print the names on the envelopes.

One major cost is pictures and or video.

Simple, cheap, 'green' DIY project I'm saving large soup cans to cover with fabric of my colors and I'll put them in the widows at the church, maybe even on the railing of the deck that'll act as our dance floor. It's a cheap Idea because I'd just be throwing the cans away if I didn't use them for flowers and no one has to know that it was soup cans because the flowers and fabric will cover that up. (I came up with that from seeing a small round vase on a florist website and I thought it looked like a decorated soup can).

Instead of a $30-50 for a guest book I'll never look at again I'm going to get a scrap book or a nice sketch book and have pictures taken of the guests and put in the book and they can write well wishes and tidbits of wisdom to us next to their picture.

Your doing most of this already but: Borrow what you can! Ebay is great place to get petals in bulk. Always ask if you can get a discount, there is nothing wrong with asking. Get what you can on clearance (like white Christmas lights are classy but safer then candles. So after Dec 25th hit the store, especially the dollar store, for a great deal). Buy in bulk when possible, tealights are done like this more then any other candle. Sign up for coupons for all of your favorite craft stores & get your friends to sign up to and go shopping with you so you can use their coupon and your own.

Good Luck and Congratulations

Aug. Bride on an budget of $5,000 for 100 guests.

Regarding the invitations try kinko's or staples. I'm sure they have nice computer paper that you can buy for those. They probably even have paper with matching envelopes. You could also try searching online. For programs, I know christian bookstores sell bulletin papers for church bulletins. Maybe they might be able to order something that is themed for a wedding. Then you can print one copy and xerox the rest off on the program paper.

have the cake made at a grocery store, and have a sheet cake in the back to cover the rest of the guests.

as for centerpieces, i'd wait til a craft store had a sale, go get some glass bowls, float some flower petals in the water, add some tea-lights floating on top and bam… centerpieces cheap and ambiance!

appoint one or two people to take ceremony pics and some of the reception, and put cheap, cheap disposables on the tables… those candid shots usually have way more life and really capture the essence of the event.

good luck and congrats

As far as the invitations go, a Michael's or Hobby Lobby (big craft stores) sell nice invitation cardstock that you could use. They also have options to use and have a Kinko's or printing store print your wording. I don't know if you know someone who has the Adobe Design Suite software on their computer (although if you know someone who works in Graphic Design or who works for a newspaper, they might have access to some…Quark would work, too), but if you did you could probably have them teach you the basics and design your own invitations on the computer. This way it might be easier to do an invitation and program that looks like they go with each other.

As far as the floral arrangements go, I think finding a wholesaler in your area would be good. If you do want to go with silk flowers, you might try an arts and crafts store like the one mentioned above. Hydrangeas look real in silk flowers and a lot of the callalillies look real, too.

You might also want to hit sales after Christmas for decor/centerpiece ideas. I don't know if you are dead set on flowers, but you might find some interesting things on sale that you could use instead. You definitely might find some pots to place the arrangements in on sale. You might also want to think about purchasing candles after Christmas. They go on sale and can add a lot of drama to a centerpiece.

It sounds like you are off to a good start. If I think of anything else, I will let you know.
