We see all the time how many woman sell items they thought up and they make good money. Now, one of us needs to come up with a scant 1/4" foot for many machines (Bernina please) and I promise that you will make a lot of money. Either have your husband do it or find someone who can do it and do a trial run to see how many (thousands) people will buy one or more. I guarantee you'd be able to retire!! I only wish my husband was that handy. But there are places you can go to with your ideas and they will bring them to life. Look it up online.
