Big Cousin is headed into second grade in the fall so her bags needed to work on different skill sets than the ones I usually create for Big Brother. I know she is enjoying to learn how to sew with her grandmother, so the first bag I created encouraged her to practice her sewing skills.
Sewing also helps kids develop fine motor skills, and in her case, strengthen her fine motor muscles even more so as she already is an active writer and used to manipulating small objects.
