Im so glad I used cheap fabric when a beginner. Some of my early quilts are not very good.
Now that Im more knowledgable I can tell when a fabric is good. Also shop online for sales of quality fabrics from last years lines. Some cheap fabrics are good quality and some expensive fabrics are crap so you need to learn how to tell the difference. You learn alot from your clothes dryer also. Ive had expensive fabric that that came out with lots of thread tangles and cheap fabric that did not shed at all.
