The steering wheel measures 17 inches with half an inch seam allowances. But after sewing all the prices together I'll need to make the wheel pattern 18 inches.
This part goes over the wheel and down over the throttlle, and will have to be shortened.
Here it is, after a few minor changes I think it will be a perfect fit. But I'm really happy with my first prototype, and dear Son in Law is really happy about it too, and is telling all his boating buddies about his talent mother in law! And since he sent them all this picture they all want to place orders too! This could be the start of something big. I will be sure to post a picture of the finished cover in the waterproof fabric. Until then, happy piecing, happy sewing,
