These are going to be a simple list of things I used or attending weddings of other brides that have used these ideas.
To save money, going with a cupcake tower, which can be cheaper than a traditional wedding cake. (Everyone gets their favorite flavor of cupcake and it is good if you have children attending.
Go simple for the decorations. Stock up on dollar-store ornaments and display them in glass bowls.
Collect pine cones from outside and let them dry. Spray paint silver or gold and pile in jars or vases. Or use them as place-card holders for a dinner party.
Invitations: I had a friend who bought nice paper & printed her own on her computer if you have a program already for it.
You can add your own little pieces of ribbon tied in a tiny bow etc. to dress them up. (you can also add a little silver heart or some little item usually found in craft store for wedding items or even making jewelry
ON RSVP you can also put a phone number on it instead of buying stamps for all of them. (Let your answering machine pick up for them to leave a message, and write that on the RSVP.)
Scour places like Wholesale and Close-out places for good buys on designer soaps and candles.
Buy in bulk at Sam’s/Costco/Price Club and whatever idea you come up with for favors (Candles, soaps, packets of flower seeds) put them in cellophane bags with a bow.(inexpensive but practical, something your guest can use)
For the men in the party, including the groom; Wear black suits instead of tuxes.
With the above in mind, if they all don’t have black suits, you can have them wear khaki pants and black/blue jackets (look in Wal-Mart they are inexpensive and nice enough for one days wearing) They can either purchase their own or you can go halves with them (the husband is responsible for this item)
DJ yourself. Burn your reception music onto a CD to be played during the reception.
You can also use this music as a favor to your guest. Buy blank CD’s and make copies of your reception music put you and your husbands name and your wedding date. (another nice touch is to add a quote, phrase or something that is special to you and your husband) Wrap them in tulle (buy this in bolts-not by the yard) and a ribbon (get this from places like Dollar Tree or again in large quantities or closeouts)
Ask friends, relatives or neighbors for where they have gotten the best deal on things like flowers, candy, gifts etc. Sometimes they are better resources than going to places that advertise for Weddings etc. You will be paying for that advertising.
