I do sewing lessons with my grandaughter (age 6)... she uses my tools and machine and with supervision has made several things ... pj bottoms, pillowcase, purse size kleenex covers, rag quilt, doll clothes, totebag some are more perfect than others but she loves it and is learning so much and it great one on one grandma time!
You could make her a needlecase and pincushion that would be special.
