I think many of the patterns are designed to specifically showcase a certain collection of fabric that the company is trying to sell. Often the pattern designers are not quilters so we may look at the pattern in a different way. I find sometimes the instructions have awkward or time consuming ways of putting the block together. Again I think that is the inexperience of the designer and most quilters can just go ahead and do it their way. The problem comes when a new quilter gets one of these patterns and quickly becomes frustrated.
