I am one who says it's Ok to stop working on a project you have lost interest in. The blocks that are already made can be used randomly on the back of another quilt if you want to; the unused fabric can be used for something else. The pattern can be given to another quilter. Quilting time is valuable to me, so if I waste a few dollars it's better than wasting a few weeks or months of time working on something that is not appealing or fun.
