Elisabrat-
You aren't alone in the panic attack- luckily I have some help here so a little of everything went into the squares (who knew 3 yr olds could help so much?) Pat on the back for you for getting as many as you have done. It won't look like barf when you are done- so dig into the craps and grab a handful to cut blocks out of it- don't second guess or put any back- just use them.
