I've been claying years and still feel like a newbie - so you're not alone there. Polymer clay is a really vast medium, so we are always constantly improving and have stuff to learn, that is what keeps it fun.
But there are no yardsticks with it - just progress at your own pace, clay when you can and enjoy it. If you have fun when you do it, then that is what really matters I think.
Enjoy the forum!
