Could SCLS purchase a printing press that could be shared and used for artistic makerspace programs
best promotion of maker programs would include an image of your "end product"
food demonstration: successful but watch the time
whether to offer refreshments
how to find "experts" (ideas for resources: local art teachers, ask your staff, ask other SCLS libraries, keep an eye on topics of interest in your community, new/existing businesses, etc)
working with community media centers/cable channels
whether to offer door prizes
