You have gotten lots of good advice, some seeming to contradict other, but all good. You mentioned a dress you are making for your daughter. Is that finished? I'll bet it is cute! And by doing that you are gaining confidence to tackle something for yourself. You can do clothing. As SewExtreme mentioned, take it easy and enjoy it. Be willing to step away when you need. You will do a great job.
It has been good for me to read over this thread, too. Thanks for asking the question. Though I have sewn clothing for umpteen years (since grade school) I needed the reminder of doing a difficult project in muslin first. I'm ready to start my daughter's wedding dress.
I hope you will share pictures of your progress. :thumbup:
