Moda Jelly rolls are always 42 pieces - there are some others that are less - you really have to pay attention when looking at them. I love Jenny too but my only issue is Block magazine does not give you the templates - if you want to make a quilt - you have to buy their template - when Quilting Quickly came out - they would include the template so you could make your own. I realize they want to sell items but I really think they should include templates.
