If you like to sew, you know that your back can get pretty cramped up quick. I have found, in addition to stretching, getting up often, and using a back support, that these hoop lapstands made by Morgan are fantastic. They make it so much easier to reach your work on a table, but can be handheld, too. I love them- worth every expensive penny. One of the few sewing “special” items I have bought and did not regret/stop using!
I live in a small town, so it helps to have a place to order or a chain that is easy to find. Hobby Lobby sells these and has sales so often, if you wait you should be able to get one half off!
