My biggest regret and lesson learned was when I made my first quilt. I didn't want to mess up the good fabric so I bought low price fabric at Walmart. I loved the quilt and my DD wanted it. After a couple of years the fabric started to fray and weaken. It pulled apart and the colors were fading. This wasn't vintage fabric like feed sack or old clothes it was cheap low quality fabric. I have never used low quality fabric in any quilt since.
