STIX Packets provide you with large and small full color and black and white images to attach to sticks (popsicle sticks or larger craft sticks). In addition, there are no prep worksheets used to further teach the targeted sounds or concepts.
The Early Sounds Complete Stix Packet teaches early speech sounds that a child can practice while associating a visual image with a sound. It's 37 pages in all!
The STIX graphics are used as a cuing strategy. In addition to these stick puppet images, there are worksheets for each sound so the targeted sound can be practiced in other contexts.
In other STIX products, the graphics are used to teach language concepts!
