It looks like, to me anyway, that you need to make up some practice sandwiches and do more practicing before tackling your quilt top. Get comfortable with some designs first. It does take practice and more practice. Sometimes it helps to draw your design on paper first or a dry erase board. Just draw it over and over until that design is imprinted on your brain and you can practically do it without thinking. Then when you get to your sewing machine, it'll be way easier and you'll be happy in the end. This of course after you'be ripped out all you did before. Good luck!
