paper straws - When I saw this post from Shannon Nicole Smith I knew I had to have some stripey paper straws at my graduation party. I found some great ones from Hey YoYo for only $4 per 25 and they come in lots of colors. Amanda is super nice, too!
paper mustaches - I know I probably could have cut these out myself, but I didn't feel like spending the money on a die cutter, and I know I couldn't have cut out the curly part without one, so I opted just to buy a pack of 100 for $12 (including shipping) from Etsy.
paper cups - I hate the look of plastic cups, so my mom and I opted to get a pack of paper coffee cups. They come in a variety of colors, but I liked the white with the stripey straws, and it gave the guests a chance to get creative when marking their cups.
balloons - I really wanted to get some round balloons, but since Party City didn't have any I decided on the polka-dot ones instead, and I love them.
peanut butter cups - One of the things I knew I had to make for my party was peanut butter cups. I made them for Christmas and my family devoured them - Maddie especially loved them - I made about 48 and they were one of the first things to go. I can't really speak for this recipe, though, because I stored them in the freezer until the night before the party, but when I took them out they got very melty. I think next time I'm going to try a different recipe.
sugar mustaches - I found these on Hey YoYo when I was ordering the paper straws, and for $5 for 10 I couldn't pass them up!
silverware basket - Thrift store. Love it.
spools of thread - Estate sale.
drink dispensers - Target
clothes pins - Bought these from Walmart and DIYed them using this tutorial (except with paper) and this tutorial. I finished decorating the entire 50 in about an hour.
