When my 3 Little Chicks go off to preschool in three weeks they will take their lunches with them. The school requires the student's lunch to be in only one container so the teachers can just pop off the lid and move on to help the next child. The leak-proof divided food containers I purchased are an awkward size requiring me to make my girls their own lunch bags. I really wanted to use oilcloth, but neither Hancock nor Jo-Ann Fabrics carried any. So, I purchased tablecloth vinyl with flannel backing for the exterior of the bag and rip stop nylon for the interior of the bag.
I sewed on a felt initial and added ribbon handles.
The rip stop nylon provided the waterproof lining I wanted.
I covered cardboard with the rip stop and laid it in the bottom of the bag to help it keep its shape.
To taper the top of the bag, I made a kick pleat then added Velcro across the top.
I wish it matched the backpacks I just made, but this lunch bag is a cute runner up.
