I usually use things that we already have for decorating. The flag bunting is from Nathaniel's birthday which I made with twine and cloth triangles sewn on. The tablecloth is a piece of old fabric I found from the thrift store for $2, I used it for Christmas last year too. The little ants on started on the table and went through the house to lead to their surprise.
These burlap bags were also .99 cents at goodwill, so I snagged a few for the girls and put their names on in fabric letters.
Jocelynne loves the American girl doll books. I found this set at a fun thrift store in Wenatchee.
Other than that I filled their bags with bubbles, play dough, sidewalk chalk, paints, coloring books and other fun things we love to do in summer. Each of the kids got a binder with their name on it. Emily will practice writing her name this summer. Jocelynne has a fun reading incentive game she is working on. I found all the printables here. I only printed the bingo card page and the coupon page. Cheers to another GREAT summer!
