Corry, I absolutely second what Janet said: even stitches are important. Just do the best you can, your skills will improve with practice. For me hand quilting is like hand writing: it's a very personal thing and looks different when it is made by different quilters. Take the time to find your own way, have fun and enjoy the process!
When I compare my first quilting stitches with the work I do today then it is a big difference. Practice changes a lot, you will see!
