Good for you! No problem. Just take your time and use plenty of pins to hold pieces together until you get good at it. It will make things lay much nicer in the end.
I love to sew. I just finished several bridesmaids dresses for my daughter's wedding next week. If you get good at it, maybe you will be doing that one day!
OR you can make furkid clothes.
Good luck. Be sure to post pics when it's done.
