On my first quilt--for a niece who had chosen inexpensive fabric--I cut all of the strips for an Irish Chain-- lengthwise. Just beginner luck as I had not trouble with wavy blocks or the finished project. And this was before I knew to "size, size, size." (Don't tell her, but she would sew strips and then I would take them out because of uneveness and redo them when she went to work.) Later she admitted that her "experience" had been to sew a pj bottom in 7th grade. She has improved and I just bought her a new machine for her very own!
Thanks to this board for all or you GOOd advice! :D
