Just weighing in on an aspect of this discussIon. Two things the newest generation of quilters hasn't had as much access to as previous generations are 4H sewing groups and and school Home Economics programs. The dollars for these and "shop", automotIve and similar programs have shifted to technology. Skills many may have learned as children or teens are now being learned as young adults. This may be why some instructors feel repetative practice hones newly developing skills. Things occur to those that have extensive sewing experience but newer Quilters don't have that knowledge to always connect the dots to a different maybe simpler way of doing things. Just some thoughts.
