Don't worry about feeling overwhelmed. I still do, after four years. BUT everyone here is very helpful. I have never asked a question without immediate answers, all which were helpful. Sure, somewhere probably thought my questions were dumb...Like, "When I change the blade in my rotary cutter....do I wipe the oil off?" But no one ever laughed, I just got the answers I needed. Plus, I got answers from all levels of quilters.
Just enjoy what you do and ask questions when you need to.
