You are probably going to fail some dishes at the beginning, it’s okay. To know how hot it is, look at the flame underneath the pot, not all dials are reliable. It’s my favourite way to cook meat, as it actually turns the heat down when you reduce the flame, unlike resistance electric that takes ages or induction that works as long as you haven’t been cooking too long. Get yourself an electric kettle or you will need ages to get warm water for your pasta.
Get yourself some gas detector and get in the habit of opening the windows to ventilate. Take the normal recomanded precaution around open flames, turn the gas off at the arrival when you leave the house for longer than 36 hours.\
A few classes to get you started are a good idea, if none of the other recommendation works you can also ask your local fabric store. (better if it is a local or small business, big chain stores might not know about that sort of things) If the budget is really tight handsewing is always an option but it takes a lot more time. You could also attempt a bit of embroidery as a start, it’s not quite like sewing but still involves a needle and you can get a cute result faster.
I hope you found a solution that works for you! I can recommend hemming skirts with bias, I find it a lot easier and faster (maybe it feels faster because I am not struggling, which I would not mind)
