My hubby is rebuilding my line, so as soon as it's done I'll snap a photo for you on the line!
Here's how I did it:
Bought a pair of childs denim overalls for $1 at a thrift store.
Cute off the legs of the overalls.
Turned the overalls inside out.
Turned up cut edge all the way around to my desired size for the bag.
Straight stitched across the bottom sewing the two sides together.
Turned it inside out.
Bag done.
