Pattern - Insulated Lunch Bag

  • 1. Print out diagram worksheet. Follow diagram worksheet throughout when completing Steps. Wash, dry, and iron cotton fabrics; trim selvages. Cut fabric following diagram worksheet, labeling each piece on wrong side. (Note: Use 1/2" seam allowance throughout. Backstitch at start and end of each seam.)
  • Nylon Lining
  • 1. (Note: Unless otherwise indicated, sew all seams in this section with fabric right sides together.) Machine-sew 4" from edges of end pieces to 4" on edges of end bottom piece, beginning and ending seams 1/2" from edge. Make two.
  • 2. Machine-sew 5" edge of one end piece to 5" edge of other end bottom piece, beginning and ending seams 1/2" from edges, moving 1/2" unsewn area from Step 1 aside. Repeat with second set.
  • 3. Machine-sew 5" edge of one divider panel to remaining edge of end bottom piece, beginning and ending seams 1/2" from edge, moving 1/2" unsewn area from Step 1 aside. Repeat with second set.
  • 4. Machine-sew long edges of adjoining pieces from Step 3 together. Begin all seams at point where panels are joined to bottom; end divider/side seams 1/2" from divider top edge. Machine-sew side/end seams to top of fabric. Clip corners at bottom. Repeat with second set completing end compartments.
  • 5. Machine-sew center compartment following Step 4, using two dividers and two sides. Machine-sew top edge of one end compartment divider to top edge of one center compartment divider, moving seam allowances aside. Repeat with other end compartment. Fold divider seams back so wrong sides are facing; topstitch 1/16" from seam.
  • 6. Machine-sew side seams of adjacent side pieces together where extended above dividers.
  • 7. Machine-sew top flap to long edge of lining, beginning and ending at joints between compartments.
  • Outer Shell
  • 1. Baste each A shell panel to corresponding insulation panel with wrong sides together, using 1/4" seam allowance. (Note: Right side of Spacetex is metallic coated.)
  • 2. Position A and B strap panels right side down on pressing surface; cover with interfacing with adhesive side down. Press well to bond, remove from surface, and trim interfacing to match strap pieces. Machine-sew straps with right sides together, leaving short end open. Clip corners, press seams open, and turn right side out through opening. Topstitch around edges using 1/8" seam allowance.
  • 3. Topstitch each strap end to shell with B panel toward shell using 1/8" seam allowance; avoid twisting strap. Reinforce end to secure.
  • 4. Fold each handle panel in half lengthwise with right sides together; machine-sew long edges together. Press seams open. Baste across short end of each handle. Turn right side out, remove basting, and press flat with seam in center of flat side.
  • 5. Fold pocket binding in half lengthwise with wrong sides together; press. Unfold; fold long edges in toward crease and press. Fold in half lengthwise; press to make 8"-long strip of double-fold binding.
  • 6. With wrong side of pocket facing up, open binding strip and align with top edge of pocket. Machine-sew binding to pocket edge along outermost fold line. Turn pocket right side up. Wrap binding around pocket edge with long pocket edge tucked in to center; machine-sew with 1/8" seam from inner fold. Trim away excess.
  • 7. Align pocket on shell front at bottom center, with right sides facing up. Topstitch pocket to shell front at sides, 1/4" from edges, leaving bound edge open.
  • 8. Topstitch ends of handle over sewn sides of pocket with handle seams against shell front. Machine-sew across handle 2" from shell front top; avoid twisting handle.
  • 9. Machine-sew shell using same method as lining, first sewing front, back, and one end to edges of bottom, then joining them at sides with seams beginning at bottom seams. Baste second end to bottom. Machine-sew both long edges to front and back with regular seams. Remove basting. (Note: Remember to begin and end bottom seams 1/2" from edges and to clip corners.)
  • Finishing
  • 1. Trim corners of shell into small curves, about 1" diameter.
  • 2. Pin one side of zipper to top edge of shell ends and front with right side of tape against cotton side of shell and teeth away from fabric edges. Pin second side of zipper to edges of back flap with right side of tape against cotton side of flap and teeth away from fabric edges.
  • 3. With machine's zipper foot mounted on righthand side of presser foot, machine-sew both sides of zipper to shell, stitching 1/4" inside zipper teeth.
  • 4. Trim corner of lining back flap to match shell back flap. With lining turned wrong side out, machine-sew top edge and back flap edge to wrong size of zipper, so seam runs further away from teeth than previous seam.
  • 5. Turn shell right side out through open end/bottom seam. Insert foam core board between shell and lining; hand-sew opening closed.
  • 6. Hand-sew visible gaps at zipper ends closed. Hand-sew corners of each lining compartment to shell through seams around shell bottom to prevent shifting.
  • Tip
  • 1. Slippery nylon fabric tends to shift during sewing, so use plenty of pins inserted at right angles to seam. Maintain even forward-back tension on seam by pulling firmly from either direction. Allow both fabric layers to pass through machine evenly without bunching or slipping.
