LOL. I don't know why someone (yes, must've been the teacher) kept them. I've always worked full time & often had a part time job on weekends, so never had the time to investigate. (How's that for an excuse??) I hope she enjoyed them!
My mom sewed & crocheted. She worked mostly with fine threads. I still have a tablecloth she crocheted in yellow & white; the flowers are yellow. There are some threads that have broken -- not many -- but I don't know how to fix it. It's the only thing I have from her. I tried working with fine thread when I was in my 20s; I wanted to make a round purple doily for my bedroom, but all I ended up with was a UFO! So I made afghans instead! Sewing/quilting has always been my first love though.
