Amandasgramma--I find it depends on the brand of fabric. Moda has so far been quite consistent in their quantities and I have not seen a charm pack for less than 40 nor a jelly roll or layer cake. Other brands, like Riley Blake and Northcott I have seen much smaller quantities. I want to say I saw a charm pack that was around $5.75 or so and thought it was a good deal but then saw it only contained 18 or maybe 20 squares. You definitely have to look at the quantity now if buying a brand other than Moda (and even then it is good to check because Moda does sell a few half jelly rolls I think--maybe I am wrong about that).
