When flipping, either hand will work. When scraping, only the left will work. Hold bowl in right, scrape with left. She also wants to only use the mixer with her left, which for some reason, causes problems witht he cord. A mixer should be either/or, and I can use it in either hand w/o problems, but she can't...........cord gets in her way. Then there are the teachers who insist on spiral bound notebooks--I suggested using them back to front. Works great and drives the teachers Bonkers!!
