Rubber stamp ideas

I just bought a huge piece of canvas and I'm hoping to make some stamped canvas bags. I thought I'd design some new stamps to cut out of erasers and here are some stamp ideas I sketched:


I made a gingko stamp but the eraser I used had kind of curved edges so it didn't quite work out. Back to the drawing board with a flatter eraser for that one. I did make myself a new feather stamp and played with it on paper:and on fabric:I should test it out on the canvas before I end up covering my whole sketchbook in feather stamps!
