    • Use a third print out or trace the pattern from the pink line down, adding 1" to the fold line to create Pocket B pattern Piece.

    Cutting the pattern pieces

    • Cut two of the body of the bag, cutting the pieces on a fold as indicated on the pattern piece.(Note: If you have allowed enough extra fabric, you can cut four so that you can double the fabric and add padding or interfacing to add body.

If you use batting be sure to check the documentation with the batting to quilt the fabric appropriately.)
