Insulated Lunch Sackby Stacy Schlyer
Materials- 3/8 yard of material for exterior*
- 3/8 yard of material for interior*
- 3/8 yard of Insul-Brite® (insulating material)
- 8 1/2” strip of iron-on Velcro®
- Thread to match
*If you plan to use a cotton material for the exterior or lining, be sure to pre-wash your
fabrics before sewing. Oilcloth and vinyl would also be good material choices as neither has
to be washed, just wiped down!
Tools- Scissors and/or rotary cutter and mat
- Tailor’s chalk or water-soluble pen
for marking - Ruler
- Pins
StepsCuttingSeam allowances are 1/2" unless otherwise noted.1. Cut two 13” x 17” rectangles from each material: exterior, interior and Insul-Brite.
2. On one short end of each exterior fabric rectangle, remove a 2” square from both the right and left sides as shown in the photo. Repeat for all lining fabric and Insul-Brite rectangles.
Sewing3. Using a long machine stitch, baste the Insul-Brite pieces to the exterior fabric pieces.
4. With right sides together, sew the exterior pieces together along each side and across the bottom edge. Do not sew the notches together!
5. Match one side seam with the bottom bag seam, right sides together, and pin in place. Sew across the fabric creating a diagonal seam. Repeat for second side.
6. Turn bag right side out. On the top edge of the bag, fold raw edges 1/2” to the wrong side.
7. Repeat steps 4, 5, and 6 for lining material.
8. With wrong sides together, place the lining inside the exterior lunch sack. Match folded edges and seams, and stitch close to finished edges.
Optional: Give your lunch tote a “brown bag” look by creasing each “corner” of the bag from the bottom
corner to the top fi nished edge. Keeping bag edge folded, stitch very close to pressed edge. Repeat for all four sides.
9. On one side of the lunch sack, measure down 1/4” from the top edge. Center an 8 1/2” strip of Velcro (the soft, fuzzy side) on this mark and iron, following manufacturer’s directions.**
10. On the opposite side of the lunch sack, measure down 5” from the top edge. Center the coordinating 8 1/2” strip of Velcro (the rough side) on this mark and iron, following manufacturer’s directions.**
11. Now you can keep your sack closed by rolling down the top edge—just like a “brown bag”!
**You may find that your pressing time needs to be longer than recommended because the Insul-Brite absorbs some of the heat from the iron.
