Hi....from the UK...you are taking me back some 35 years with the hexagons ...first ever quilting I did aged 13 at school! I am sure they are for a hexagonal (Grandmothers garden quilt)You need to cut a piece of paper in the same shape but half an inch smaller, pin it in the middle and then hem round the paper....at school we had piles of fabric hexagons and matching piles of paper....great way to teach children a traditional way...I remember having the flower patces all over my jeans....very with it !
As for the other article...pretty sure it is a chart reader...maybe for cross stitch, the small piece looks line it is used for reading individual lines of the chart and the other bit looks like it might attach to a stand.....hopefully someone will recognise it.
