My bff wants a bow tucks bag, but she wants it bigger, so she can use it for work.

The pattern calls for the top piece 8.5 x 19 and the bottom piece 6 x 19. The end result is the front and back pieces being 14 x 19. I figured that I can extend the width from 19 to 21 so I can still maximize the fabric, but what would I do for the other part??

I hope the question is clear. It's confused me to try to figure out and trying to explain it has further confused me. lol. The math is NOT my strong point.
