Unfortunately I didn't get a good photo of the gift boxes for children to take home after the party. They are lined up on the bench in the background of this photo.
This is the only photo we have of the 15 assorted boxes. It is my birthday girl blowing her nail polish dry.

We just used plastic strawberry boxes that we saved for several weeks leading up to the party. We put a little coloured shredded paper in each box, a little lolly bag and a couple of little toys. We put a strip of patterned paper around the outside, some ribbon and then finished them off with a pom pom garden critter that we also made.
These didn't cost much at all. We recycled strawberry boxes and used paper and pom poms that we had in the craft cupboard. I ordered the toys from ebay well in advance because it worked out cheaper that way, (magnifying glasses, bird whistles and bouncy balls).
