GroovyNoodle wire. Some is good; LOTS is better.
We absolutely love our GroovyNoodle wire, with its super flexibility and silicone-jacket insulation in 7.5M "casual use" spools. For more ambitious projects that need more length, we now have our GroovyNoodle in value-priced 50 meter spools!
It's more of our favorite 24AWG wire with a whopping 40 strands of 0.08mm tin-plated wire, UL3131 rated for 300V and 150°C, available either as individual spools or a color assortment 8-pack! (Sorry, not in the same style box as the small spools - it's too cumbersome)
