We have -40C outside at the moment. Fortunately the shop is always heated.
Use whatever you can get your hands on to practice and learn tool control. Anything you can find on the ground, a dead branch, scraps from a cabinet shop or similar, pieces from an old piece of furniture, then you can turn until they are too small to be safe. Don't use tubes until you get the hang off it. You can also use practice wood to get a scratch free surface and then confirming by putting a finish on it. Repitition makes you a good turner.
Lastly. Welcome to the forum.
