It is a pretty curved glass medallion with a diameter of 25mm on which you can place your embroidery needle so that you no longer lose it or stick it in your canvas.
How does it look? a magnet is stuck on the pendant (on the back) and you have a second magnet hanging on it. You remove this second magnet by sliding it, then you insert your embroidery canvas between the two magnets and you place your needle on the glass cabochon.
If you don't embroider, this pretty accessory can simply serve as a magnet, for example to hold your knitting or crochet pattern on a metal table, or as a decoration.
Small embroidery tool, made in France by Made in Laine in small series.
