- Create optional inside pockets, remembering that 1/2" in from all edges is needed for seam allowances and that 2 1/2" in from the bottom 12 1/2" edge will be used in the bottom of the bag.
- Place lining pieces, wrong sides together, aligning all edges.
- Sew one bottom 12 1/2" edge and both 10 1/2" edges using a 1/2" seam allowance.
- Apply a seam finish.
- Finish the bottom corners the same way you did for the body of the bag.
- Place the bag (right sides out) inside the lining (wrong side out on the lining so right sides are together).
- Match edges and seams.
- Pin in place.
- Sew the layers together 1/2" in from edge, leaving an opening to turn the bag right side out and to slide the optional bag base/bottom through. (The amount of opening will vary on how much batting and interfacing you used.)
