Really starting to dislike when I forget about Kathryn Totten's storytime books...I'm sorry, but they're just not very good in my opinion.
The crafts are either too simple or too complex, they're very vaguely (emphasis) tied-in with the storytime theme and many of them only take a few minutes to do, while NOT a bad thing for kids with shorter attention spans, but I hope you have back-up crafts because for a typical storytime audience, they'll be done with them in under 5 minutes, THEN what are you going to do?
