"Help yourself to take home..."

I'm working on a card that will be displayed at a wedding reception. We will have lots and lots of cookies available (it's a western Pennsylvania thing) and we have little boxes with a wedding-date sticker on them so guests can take some cookies home. ANYWAY, I'm hammering out the language to put on these cards that will direct guests what to do. Here's how I have it worded currently:

"Please help yourself to take home some treats in the boxes provided at our cookie table."

Is that correct-enough grammar to use?

P.S. Please don't correct my forum-speak spelling & grammar, only the above line in quotes
