Sew4Home shares a tutorial for their Pocketful Zippered Picnic Tote. You can pack a whole picnic in this bag! The large tote is insulated, with a wipe clean fabric on the inside and an outdoor fabric on the outside. Pockets line the interior of the bag to give places to hold drinks or napkins or other smaller items. Get the tutorial at Sew4Home.
