@Rheall Most effective for me are: small zip-loc bags (search “Flossaway” for a kind targeted to crafters); a piece of card with notches cut into the edges that can hold loose threads in place (and on which I can write to say which notch is which colour).
@Rheall my grade 11 physics teacher had to leave the room during my working on the pulley lab, he quote "could no longer stand the carnage". 😂
@Rheall I have several of these. Hook many threads in, hook one thread in.. there is space to mark which threads rest where and you can also park needles. Picture from the internet, not mine.
