I am a proud participant and organizer of Flannel Friday.
Flannel Friday is an amazing community of librarians sharing ideas and how-tos about props, flannelboard stories, puppets, and other tips and tricks for storytime.
There is a blog to learn more: http://flannelfridaystorytime.blogspot.com/
A Pinterest archive of past ideas.
A Facebook community for questions, sharing, and commiseration.
An awesome blogroll if you're looking for more online storytime librarians to follow
Flannel Friday is so much more than an idea archive; you can learn why Flannel Friday is important to me HERE.
