Creating the perfect picnic is no picnic. There are too many factors that need to be considered. The weather – without sun you're lost – zero dogs, pigeons or insects, an enthusiastic guestlist who deliver on supplies and, of course, a vast array of implements that really only work in the picnic format – spending the rest of the year languishing in cupboards. But don't be disheartened. This week is National Picnic Week, a ten day celebration of all park-based, rug-bound socialising, inspiring a city-wide dash for sausage rolls, Victoria sponge and Pimms-in-a-Can as we head en masse to the nearest green space. To help you on the way to picnic perfection, we've gathered together the best in enamel plates, bijou barbecues, indulgent blankets, bags to carry it all in and a delicious garden fragrance to ensure your outdoor idyll smells as good as it looks and tastes.
