Silver macramé is made by starting with an extremely thin wire, 0.25mm. or 0.3mm. in diameter, which is then twisted into a four-ply wire, being careful to keep all four strands properly aligned. Finesilver (999 parts out of 1000 pure silver, as opposed to sterling, which is 925/1000) must be used to obtain the necessary flexibility.
Once the basic strands have been made, they are knotted in similar fashion to macramé threads, except that sometimes a strand must be pulled through a tight place with a tiny crochet hook. Also, extreme care must be taken to keep the strands properly aligned.
Soldering the macramé knot to silver sheet also requires close attention, since the strands are still very thin and can easily be melted down by mistake.
