Because I often have people tell me that they can't believe I "could see that," I have realized over the years that not everyone finds the differences in shapes as easy to "see" as I seem to. Today I found a test that helps you determine your ability to discern the vague differences in shapes. This could be a great resource for quilters and instructors. You might enjoy trying it!
