Good luck with your new business venture. I'm a beginner at sewing as well....I found it's good to start simple...I'm still in the "straight line" phase. lol. I've already made a few blankets, next I want to try weewee wraps, and then I already have a doghouse pattern that I want to try. There's so much I want to do, but then I get so frustrated when my thread gets jammed in the machine. lol
Good luck! Can't wait to see the clothes you come up with! Make sure to make some cute items for the boys....they always seem to get left out of having cute clothes.
