You will need:
garden wire 2 mm thick
clamping and shaping pliers
superglue
cotton or wool
Chop a long enough wire and use the pliers to shape the name according to your imagination. When the word is complete, in the places where the wires are close, create space again and pull them apart.
Now you can wave the wire. Apply a second glue to the end of the wire to the wool and start wiping tightly. Every 1 to 2 centimeters fix the string to the wire with a second adhesive. You can rewind multiple colors at the same time or alternate.
Then the rest of the word remains the original shape.
