Precut jelly roll strips are not the same thing as bias strips. Bias cut strips must be cut on a 45-degree angle, while jelly roll strips are cut across the width of the fabric.
Precut strip sets are sometimes called by a different name such as rolie polies or bali pops (usually for batik fabrics). Don’t confuse them with Honey Buns – those are 1 1/2” strips!
