I still have my beginning sewing box from sixth grade! I have som e fabric and embroidery floss from my grandma. The first pattern I sewed is in there. Rickrack is in there. It was one of my favorite things to use back then. I have buttons of all sorts. When you are young, everything needs at least one button. I also have a thimble, all kinds of needles, sewing scissors with my initials on them, tape measure, spools of neutral threads, a seam gauge, and I could go on. Maybe this will give you some great ideas.
If some people who mean something to her contribute, she will be 45 some day, and holding that stuff remembering every person who gave it to her! She will also look at that first clothing pattern, remember sewing it, wearing it, and laugh at the style from way back then!
