I love a picnic whether on the carpet, in the backyard, in the local park, on the beach or dock. Here's a few things that keep me picnic party ready.
Ikea has the best napkins for 1.49 pack. I always stock up when I make it there.
Toss bright colored flatware in a bucket and bring out for last minute park runs. The Dollar Store usually has a nice selection.
Wasara is a japanese line of picnic productions that are biodegrable and can be reused for a few uses if they don't get "wet". Branch Home sells a kit for 8.
Another option for green friendly folks is this party kit from Branch Home.
While visiting Nantucket a few years ago, I fell in love with a cute shop and the owners had put together this book. It's been dog earred like crazy and while it's not my kitchen bible, a few times each summer it gives me inspiration. Recipes for lobster rolls and clam bakes get me there without actually going. Amazon sells.
