Here are some things from our wedding last month. My husband and I decided to spend the majority of our money on the venue & food, so pretty much everything else was DYI.
I designed and printed all of the invitations, programs, thank you cards & the reception program.
Both of my parents have passed, so I had little framed pictures of them in the flowers I carried. We got all of the flowers the day before at the local farmer's market. They were a whopping $125 total (for everyones flowers!)
My mother in law started making homemade caramels months before the wedding and froze them as she went. She ended up making over 600 individual caramels (each guest got 3 different flavors)! We put them in little bags that I bought at a local paper store ($15 for 500, now I have about 300 left!) and used a variety of red, gold and black ribbon I had kicking around to close & tie temporary tattoos onto.
I made the tattoos and had them printed online (temporarytattoos.com), I think I paid $75 for 1000 tattoos. We put leftover tattoos in a basket, along with water bottles and paper towels so guests could apply during the reception.
The photobooth was big hit. We used it instead of hiring an additional photographer. Everyone loved it. The attendant also created a guest book on the spot so guests could sign a copy of their photos for us with a message.
Instead of buying a cake cutting set, we used one of the husbands old knives. He was into ninjas and army men as a kid and for some reason had a big scary "trench knife". We tied a ribbon on it and it was perfect. Notice the brass knuckle handle!
During the planning process I had joked with my bridesmaids that I was going to make them wear top hats and carry bird's nests instead of flowers. Well two of the girls made these awesome top hat bird veils. We all loved them and rocked them at the rehearsal. We decided to wear them at the reception too.
I brought some mustaches to the reception. Between the top hats and the staches, everyone knew who the bridesmaids were!
We decided on a very simple cake, without any decorations. The family members that did our flowers also were in charge of decorating the cake. Since we had a bird theme going on, my sister made the bird toppers from parts of our mom's wedding dress. We also had a bird cage for cards (not shown) with another set of birds perched on the top of it.
And finally, I'm not sure if you can call it DYI, but my husband is a professional musician and plays with a wide variety of artists. Instead of paying for music, we asked my husband's musician friends to play for us as a wedding gift. We had a total of 6 musicians during dinner and two bands with Ipod lists inbetween. Everyone loved it!
It was a lot of work, but so worth it!
