Good for you Carmen!

I'll be the first to offer advice: always be sure your top thread & bobbin are threaded correctly (you'll know if it's wrong because your stitches won't be right). Get yourself a good sewing encyclopedia type book for when you need more info on something. Google is your friend too! (TONS of sewing videos online.)
Have fun. In no time you'll be whipping out all sort of stuff for your girls! Can't wait to see your very first creation.
