My thoughts (you will get many others)--
You don't have to use a hoop if you baste really well. I was taught on a hoop but do it both ways--with or without--depends on my mood. Your stitches will improve over time. Just try to keep them even and it will be fine. If you are going to use the hoop make sure your quilt is not hooped too tightly. The quilt has to have some give and you should find that your stitches can be worked a little easier.
