My son needed a lunch tote for school- or rather, I wanted him to have a special one made by mommy- so I decided to show how to do this as part of the 30 Day Grab & Go Gift Series. I’ve made lunch bags for people before- they’re a fun gift and useful if you know the person packs a lunch. And they’re AWESOME for kids. What kid doesn’t love having a unique bag for school?

So I brought G (almost 5 years old) to the store and told him he could pick out his own fabric. What does he choose?

A 4 year old's idea of fun soda fabric for his lunch bag.

“I want the soda fabric mommy!” (as someone shopping nearby snickers, overhearing this)

Now y’all know… sometimes it’s worth the fight and sometimes it’s not. Normally I’d say whatever. But I figured this was a good time to redirect because I didn’t think this fabric would send the right message at preschool. Haha!

Fortunately he found some cute road signs fabric which I immediately snatched up like YES! WE HAVE CHOSEN! Let’s buy this before he changes his mind.

How to Sew a Lunch Bag

Rough finished dimensions: 10″ tall, 7″ deep, 8″ wide. 

Step 1: Cut your fabric according to the instructions on the sewing pattern. My pattern making is amateur so make sure to check out my instructions on assembling my patterns.

Step 2: Baste or Quilt your Insul Brite to the exterior fabrics

Step 3: Sew all the sides of your exterior fabric right sides together, then sew bottom to the sides (again, right sides together)

Sew bottom onto bag exterior.

Step 4: Do the same with the PUL interior fabric

Step 5: Turn PUL interior right sides out, then stuff inside the exterior fabric- right sides together. Pin.

Step 6: Sew around, leaving an area to turn and top stitch.

Step 7: Turn and top stitch.

Step 8: Add strap. I make sure to back stitch over the straps quite a bit so they won’t come off.

Step 9: Add hook & loop. You may want to add these before you sew everything together, but I find it easier to place it after sewing it altogether.
