During clearing out the home of my deceased parents, I found some plates which are tools for either knitting, stitching or sewing. First I thought they were part of the knitting machine Brother KH-588, but then I found others in a completely different place, so I assume that they are not related to this machine. These are thin metal plates of about 10 cm in size each, with some sort of clamps on them. Does someone have a clue what these things are, and what they are used for?
I think these items are shapes to make yarn flowers and a kind of lace for which I can not find the name.
This search results page (link to pinterest search results) shows a series of different shapes which each have a set of pins sticking up or out for string to be wound around, going from a stick over the middle of the shape, and then to one on the other side of the shape, forming a flower shape which has all yarn crossing in the middle. That middle is next sewn together, so the flower gets structure.
When used for that lace method there can be more creative winding and a lot more 'sewing' or embroidery over the yarn.
Your templates are up-side-down in the picture, you would work on the flat side.
The system in these templates seems to allow to retract the 'sticking out' pins.
