For her I made some extra items for a total tie-dye outfit. (BTW anyone wants a tutorial?)
The cake was a giant cupcake with all flower power type things (see here) and I made paper table cloths for the theme.
Every girl got a little tub with beads and flowers to string, which started with huge enthusiasm but was abandoned by all to play with abandon.
And my two cousins took the photos for me so I really can not take credit for the above.
