I have not done any crochet in years, but do know how. I do know that the tension being the same takes time and practice. I'd just try making something simple like a winter scarf as a first project. If it gets out of whack, just pull it out and try again. Use a simple stitch and complete something easy. Then try something harder next time. But a scarf is a good first project. Making something like a baby blanket or afhgan is a good project too but you have to have your tension pretty consistent for it to come out right.
I also made rag rugs from scraps using those giant crochet hooks, that was a fun project and a way to use old fabric you might have or acquire cheap.
Hopefully some expert crochet folks will chime in here and help you a bit more.
