so, are you not willing to teach him some quilting? I would be happy that now that he has figured out a machine- and knows quilt piecing entails straight seams that he thinks he should take that next step= my sons and nephew all started innocently enough- then jumped in with both feet all 3 of them challenge me regularly- young men are adventurous- don't worry about *old stuck in the mud rules*, have great color sense and if they have a desire they should certainly be encouraged. after all- being able to sew a straight line is the foundation to successful quilts.
