Signed T-shirt

• A large T-shirt that everyone can sign provides party decoration and serves as a memorable gift for the guest of honor. For instance, if your father is celebrating a 60th birthday, purchase a T-shirt in the style that he wears the most, such as a V-neck, T-shirt with a pocket. Purchase a large frame that the T-shirt will fit into and encourage all the party guests to sign the T-shirt with their names and a short message like "Happy 60th birthday" or "We love you." Frame the shirt and display it during the celebration, and formally present it to your father at the end of the event.
  
  

Silkscreen T-shirts

• If you're planning your child's birthday party, have the T-shirts made ahead of time featuring a picture of your little one for guests to wear to the celebration. Get all the sizes of family members who'll be attending the birthday party, and create a shirt that displays your baby's first hospital picture if you're organizing her first birthday event. If you're having a small party for your daughter and her best friends, and already have a photo of the girls, have this picture transferred onto T-shirts after getting the correct sizes from the children's parents. Present the shirts to each child at the party, and allow the kids to paint or sign the shirts at the celebration and take them home as favors.
  
  

Age T-Shirts

• A T-shirt that displays a milestone age is appropriate for the guest of honor to wear at a birthday celebration. If you're putting together a party for your wife's 40th birthday, create a T-shirt for her that is fitting for the season, such as a long-sleeved shirt if the party takes place in the fall or winter. Have a T-shirt designer print the phrase "Happy 40th birthday (your wife's name)" in the center of the shirt in a font that fits your wife's personality, like cursive if she's refined and sophisticated, or large, round letters to denote her fun and upbeat personality. On the back of the shirt, have a designer make a short list of 40 things you love about your wife, like "she makes me laugh" or "she's beautiful" to make the shirt a keepsake that she'll cherish for years.
  
  

Favorite Things T-Shirts

• Work with the guests attending the party to come up with a T-shirt "uniform" everyone can wear to the event. If you're having a small get-together for your best friend, purchase T-shirts in her favorite color, and accent each T-shirt with the things she likes best. For instance, if you're especially crafty, glue synthetic pearls to the collar of the T-shirt to resemble a string of pearls if she loves fine jewelry, or add strips of silk to the sleeve hems of the T-shirt to display her fashionable taste. Make enough of these shirts for everyone who's attending, and work with the guests to further design your best friend's shirt by sewing on patches that represent things she enjoys, like a sun to represent how she loves the beach, or a spoon as a sign that she loves to bake. Present the shirt to her as a group gift at the party.
