I have the large strip tube ruler and am a HUGE fan of this ruler and Cozy Quilt Designs patterns. Complicated looking quilts made easy. She has many, many videos on YouTube showing many of the patterns. For me, I enjoy her tutorial videos as much as Jenny Doan's, I subscribe to Cozy Quilt Designs and when a new pattern video comes out I receive notice. I wouldn't hesitate in getting the strip tube ruler and most definitely buy her patterns that are strip tube friendly. (Not affiliated just a big fan)
