Luckily (because I'm neurotic about saving anything made of cardboard) we have a few children's sized shoe boxes knocking around - they are great for all sorts of kid craft projects. I love repurposing things - have I said that before?
My eldest took a great deal of time painting on glue and dipping the box & lid in copius amounts of pink glitter. After the glitter and glue had dried I added a glue wash on top (1 part glue 1 part water) to try and encourage the glitter not to shed everywhere immediately. There is SO much glitter on this box - my eldest bunny is slowly convincing me that when it comes to young girls - there is never enough glitter in your life!
After the glitter had been added I lined the inside of the box with some scrap quilt batting and a piece of purple velour left over from our Princess Tea Party. I stuck them all lightly down and together - adding more glue to the top edge - I favor Aleene's tacky glue for fabric sticking.
The inside of the top of the box is painted pink. We decorated the top of the box with an old broken purple butterfly necklace (yes I save that sort of thing too) and with the name of the birthday girl. I cut the name out of white felt which had some silver lamé stuck on top.
Please do not forget about the charity I Spy quilt - we are still looking for scrap fabric donations.
