Arrange the metal rings as you like to create a decorative pattern. First, cut a strand of macramé yarn about 4 meters long. (If this length is not enough for your knotting, you can always continue later with another piece of macramé yarn).
Take the yarn double and attach it to the metal ring with a
lark's head knot. Then tie the metal rings around using the classic
square knot from the macramé technique. However, instead of tying the two middle threads, tie the knot directly around the metal rings.
If you want to connect metal rings together, simply tie both metal rings together with square knots. Design according to your personal taste: once your macramé strand is worked long enough, shorten the ends of the yarn with scissors and fix them on the back with VBS craft glue.
Start over at another point in your metal ring arrangement with a new lark's head knot and make more decorative cross knot strands this way.
Attach your new decoration to the wall - your planting aid is ready!
