My favorite thing was the Vinyl banner we had printed for my son's party. It is 2 foot by 4 foot and hangs vertically with his name, an anchor, and "Honor, Courage, Commitment" at the bottom. At his party everyone used a black sharpie and signed it. It is hanging on his bedroom door now. I took a picture of it and sent it to him (he's at bootcamp now) so he can remember everyone praying and supporting him while he's there. It also reminds me how much everyone loves him.
For our sons party we had a banner made and I ordered from a company online the Navy emblem for the cake. I had Publix bake the cake and I added the emblem. I had all navy blue plates and utensils. I had yellow table cloths and napkins, I rolled the utensils in the napkin and tied it with a navy ribbon and a lifesaver. I found yellow buckets and putt the rolled napkins in the buckets. We had blue and gold star balloons. We have been releasing one balloon a week since he left. His dad and I each released on the first day he left. I found at Target note cards with an anchor on the front and I had all the guest write something to him and I will include one or two in my letters. We had lots of good food and friends and he really enjoyed the day. I think I was able to attach the pictures of the banner and cake. Computers are not my thing so I hope it worked.
