Here's the schedule:
Day 1: Getting started - cutting and fusing pieces
Day 2: Starting Exterior of bag
Day 3: Finish Exterior of bag
Day 4: Make the Lining
Day 5: Finish the bag! (That's today!)
Joining lining and exterior
Zipper tabs - completing bag
This part is finnicky: Lay the zipper casing flat against the open side at top of bag, lining up center of zipper to side seam. Smooth out bag and casing as much as possible and clip in place. The zipper casing will extend past the side of the bag, that's ok. Sew a line of basting stitch across the end of the bag and trim excess zipper casing, leaving a 1/4" seam allowance.
