One must be careful when buying pre-cuts and never assume for instance that all rolled up bundles of strips are equal to a Moda Jelly Roll. Always read the label and see what you're getting! "Design Rolls" in my experience are generally 20 strips and run $14-$19 while a true "Jelly Roll" will be 40 strips, in the $35+ range. I do like being able to collect an entire fabric line by purchasing a charm pack or layer cake, but like all fabric, not all pre-cut offerings are equal.
