First, I cut two pieces of material a little bit wider and taller than I wanted it to make room for seam allowance. I sewed a 1/4 inch seam on three of the sides.
Next, I cut a piece for a pocket. I cut mine 14 inches wide and six inches long. I sewed a rolled hem along the top.
After that, I sewed three sides to form a little bag. I sniped the corners to make it lay better.
Then I attached it to the bag. I unintentionally made a double pocket because I sewed it on by only attaching three of the sides.
Then came the straps. I cut them twice as wide as I wanted them and folded a 1/4 inch amount all the way down them and folded them in half.
I sewed a small seam down the open side. This method is easier than turning the straps right side out but that method would work just as well.
The lining came next. I sewed three of the sides together leaving a three inch gap along the bottom.
I then attached the lining straps and the outer part of the bag together.
After that, turn it right side out through the slit left in the lining.
I then stitched up the slit in the bottom of the lining.
Iron it so it lays right. the sew a top stitch along the top to keep the lining from coming out.
The finished product!
