I have been quilting for over ten years mostly self taught but I have gone to big quilting shows and taken lessens from some of the top teachers out there.I would say most quilters help each other out,you do not say where you live but if you lived near me you would be invited to my quilt studio so I could show you what your doing wrong or right.First off cutting accuratly is most important,second learning to sew a scant 1/4 inch seam,third understanding the instructions,and yes pressing the right way your back should look as good as your front so when you start quilting you don't have lumps that your sewing machine has to go thru.A good ruler and rotary for cutting.I am a long arm quilter and live in Langhorne Pa.Ask your questions we would all like to help you become the best you can be.
