Take your pieces to your LQS and ask for advice and tips. Please post pictures of the front and the back so we can see what your issues may be. Ask a lot of questions of others at your LQS -- there is a wealth of information out there and people are willing to help. I highly recommend the book Quilter's Academy 1 by Harriet Hargrave. It contains a wealth of information. If you read it and make the quilts in the book your skill level will be amazing. Good luck in your quilting venture.
