When making a Lunch Bag, you can either use pre-cut material or make your own. The base for your lunch box should be a cardboard box. If you'd like to make a strap, you can use interfacing. You can also double the cotton fabric and sew the two pieces right sides together. The seam allowance for this project should be 1/8 inch. Once your fabric has been cut, you can begin sewing the strap and lining together.
The first step is to print the top flap pattern. To cut the fabric, print the image at full size, without scaling the image. It should be centered in the middle of the fabric. Pin the pattern to the short end of the fabric. Trim the corners using the fabric snips. Be sure not to pin the pattern through the Vinyl Fuse as this will leave permanent holes. Next, sew the flap to the body of the bag.
To create the Top Flap, print the downloadable PDF pattern. It is best to print the image at full size, without scaling the image. Be sure to follow the measurements provided in the PDF. Once you've pinned the fabric, line up the short ends and sew. If you're using Velcro, pin the bottom flap to keep it in place. Avoid inserting the pin through the Vinyl Fuse or you'll end up with permanent holes.
To construct the bottom flap, pin the two pieces right sides together. Match the front and back seams of the bottom piece with the center of the hinge piece. Sew the zipper by matching the back seam of the bottom piece. Once the zipper is in place, use basting to ensure the stitching doesn't show. You can also sew the top edge of the bag with a 1/8" seam allowance. There is no need to worry about the zip.
The fabric of the lunch bag is important. There are different types of fabric. Waterproof linings and Insulated fabrics are popular choices. Besides that, the fabric should be able to handle various types of weather. If the lunch bag is made of waterproof material, it must have a PUL waterproof lining. For cooler bags, the fabric should be insulating. Oil cloth and Ripstop nylon are good choices. Moreover, the fabrics are wipeable.
Once you've chosen a fabric for your lunch box, you should hem the bottom piece. The bottom piece must be symmetrical. This will prevent the zipper from slipping. During sewing, you need to match the front and back seams. You can also make a lunch bag that is lined with fabric. It will not only keep your lunch items protected, but will also look good. Once you have completed the sewing, the top flap and the sides should be symmetrical.
