I know exactly what you are talking about because I do the same thing. First I worry I will cut the fabric wrong, need additional fabric and not be able to find more. Then after I have completed the quilt, I hesitate to use my scraps because I'm afraid the quilt will get damaged and I will be unable to find matching fabric to repair it. I know the "hoarding master" lives at my house but, I was not aware that one of his favorite spots was my scrap box .
