We seem to see more and more oilcloth being used in creative projects these days. There are so many prints and colors, and it wipes clean easily- making it perfect for this lunch bag project. See the simple directions below...
The directions via Martha's site:
Lunch Bag How-To
Cut main piece 29 1/2 by 8 inches and two side panels, each 12 1/4 by 5 inches.
1. Fold long panel, inside out, into U shape with 5-inch bottom.
2. Make 1/4-inch cut at bottom corners of side and middle pieces so bag folds smoothly. Sew-in side panels, leaving 1/4-inch seam allowance.
3. Turn right side out and top-stitch all around, 1/8 inch from edge.
