I have researched individual blocks when I am looking for something. Say you wanted something Halloween. Each one could be looked up by itself and then you could put them together how you want.
The puppy and the bathtub were two different drawings that I found online. (the towel rack I drew myself)
The pumpkin was from my Halloween decorations, the apples were a picture I found.
I realize that mine are machine applique and you are probably looking for regular blocks, but I am sure you will find something that will call to you.
Good luck!
