Hi Denise, depending on what type of container you store your starter in, you may not see it quite double in size. For example, if you have it in a wide bowl, the surface area is more spread out and the actual rise will seem less significant. Look to see that the starter develops an airy, almost fluffy consistency and has bubbles throughout, rather than just on the surface. I hope this helps!
