Yeah I have always found it hard to decide what to make. Having small stuff that can be made easily is great but you need something big to bring in the crowds so to speak. Your guitars and slides are so cool though and unique, you don't want to stray too far from those. The inspiration will come, I write all my ideas down now , it is easy to forget. Then if I am trying to think something up I refer back to my note book, surprising what I come u with sometimes.
