I want to take your class! Mine did not include any curvy pieces at all.. we used the New Sampler Quilt book by Diane Leone and it was pick the ones you want to do I will help everyone on their blocks and as newbies.. you go for the easier ones and with twenty students what teacher could stop and teach each and every different pattern to each student in six classes? I am to this day scared to death of those curvy pieces and avoid them. love them but avoid them.
