How to choose the ideal needle and thread?

This question is very common and does not have an exact answer. The needle will depend on the thickness of the yarn, so it changes with each production. You can find this indication on the yarn packaging, and needle measurements can vary from 0.5mm to 25mm. You will also find a multitude of needle options, which can be made from bamboo to aluminum. The best type depends on what is most comfortable for you, so it's important to test to find out what suits you best!
