building a sand box

our thoughts are on the same page here! i have been thinking about a sand box to put on our balcony for hailey.

here is one example of how to build a sand box from the diy network.

like this one by step2, for example:

i found that one on ebay for $85. you could definitely make one like it for WAY less.

another thing i was thinking is, she will need a water proof apron if we're going to add the water section. something like this one:

target already has their pool/beach toys out, so we'll be all set!
