It’s still July so I am definitely not ready to start thinking about that event that happens in August where kids load backpacks and books and head off, out of my world and all the fun that is summer. (I will not say the words yet.) I hate it! I need summer to last so much longer! But, I know some of you are already counting down, so, I’m going to start giving you a few things to think about, sew or do to get ready! (That part is at least fun right?!)

Today I have a darling little kids insulated lunch bag pattern and tutorial to sew. It’s fairly simple to sew and turns out really cute! Like I just keep looking at it because I am so in love with it! And isn’t this fabric fantastic!?

It should fit a good size lunch for the kiddos and it is insulated. Throw an icepack in there and you should be good to go!

Kids Insulated Lunch Bag Pattern and Tutorial:

Supplies Needed:

  • 1/2 yard of fabric (you make have some extra) I got my fabric at Stitch Stash Diva
  • 1 yard of thermal interfacing
  • Small strip of Velcro

Cutting Guide:

From each of your fabrics and your thermal interfacing, cut-

  • 1 piece that is 8 x 13 1/4 inches
  • 1 piece that is 8 x 10 inches
  • 2 pieces that are 10 x 4 1/2 inches
  • 1 piece that is 8 x 4 1/2 inches

From your main fabric cut-

  • 1 piece that is 11 x 4 1/2 inches

Lunch Bag Pattern Sewing Guide:

First we are going to make the strap. Take your piece of fabric that is 11 x 4 1/2 inches. Fold it in half lengthwise so that right sides are together and sew up the long side:

Turn it right side out and press it flat.

Then, fold that in half lengthwise again and press. Sew up the long side one more time. It should now be 4 layers thick:

Now, grab your main fabric pieces. Begin to piece them together by taking your front piece (8 x 10 inches) and placing the 10 inch side of it along the side of one of your side pieces (10 x 4 1/2 inches) with right sides together and sew up the 10 inch side:

Then grab your back piece (8 x 13 1/4 inches) and sew it to the other edge of the side piece so that the excess fabric from the back piece is left hanging at the top, BUT, as you do this, you need to sew the strap in place as well. To do this, place it between the back piece of fabric and the side piece right near the top of the side piece-just about 1 inch from the top. Just pin it in place and sew it in there between the two layers: (Sorry, I forgot to take a picture of this step while I was sewing, so I am showing you what it looks like when the bag is complete. Hopefully this still makes sense.)

Then sew the second side piece to each of the front and back pieces in the same way.

You are going to do all of this now with your inner fabric AND your thermal fabric. Simply place the thermal interfacing on the back of the inner fabric and sew it in place with it as you follow the above steps.

Once you have all of your sides and front/back sewn together, we need to add the bottom piece (8 x 4 1/2 inches). To do this you need to carefully pin it around the bottom opening of your bag:

Then carefully sew that in place.

Now you have the inner and outer parts prepared. Let’s sew some velcro in place. Cut a piece that is about 4 inches long. Place on piece on the front part of the main fabric:

And one piece on the back piece of the inner fabric:

Then sew those in place.

Now let’s put it all together!

Turn the outer/main fabric inside out and stuff it down into the inner part:

Now you are going to pin it so that the sides of the outer and inner match up as well as the front and back.

Then you will sew beginning at flap. At the top, left side of the flap sew down the side of the flap, then turn and go across the side of the lunch box, across the front, and then up the other side and flap LEAVING THE TOP OF THE FLAP OPEN.

I have a video tutorial of this, but it’s from the messenger bag tutorial. It’s the same concept though, so if you need a better visual of this, try this video tutorial here.

Before you turn this right side out you need to clip the corners. (This means, cut a few small slits in the fabric right up to but not through the seam, at the corners. This helps it lay flat when you turn it.)

Now, reach inside and pull the inside out and turn it all right side out and get it tucked in how it should be.

Now you will need to do lots of pressing to get it all nice and flat.

Fold the top of the flap inward (so that each of the fabrics is tucked inside) and sew that part shut.

Last, you need to really press the sides. We want to form a pleat on the sides, so fold them in and then grab your iron and really, really press it until it holds its shape:

And now you are done! Hope you love this cute lunch bag pattern.
