It appears much like Jenny Doan's @ Missouri Star Quilt, newest tutorial just a smaller width strips version ~
I agree with copyright being extremely confusing and there have been numerous threads here and other boards, with supposed expert advice on both sides of the fence.
The more opinions expressed here about copyright the more confusing it gets. Since I don't sell my quilts or projects it is most definitely a hobby and the things I make are made for gifting or personal use, the copyright debate that goes on and on doesn't seem to apply to me personally.
Again as rush88888 stated in her post, her final statement, ..."do what you feel is necessary."
