I have been making these for my kids...I cut up 99 cent vinyl table cloth material for an easy wipe inside - kids are always so messy
I really like this bag because it fits plastic containers, thermos, etc very nicely. I have visions of making a patchwork patterned one for my sewing supplies too.
Here is the online tutorial:
