At a cost of about 11 bucks, I would say go for it.
Every newbie sewer needs some help, and not necessarily for a live person.
Don't most of us use a 1/4 in foot to help us make more perfect seams. And a cutting mat, ruler and rotary cutter to cut more accurate pieces. I still use all these things and have been quilt making for many years. I could never have made over 150 quilts if I hadn't found all these gizmos to help me out.
