I'm planning a quilt project to keep me busy over the winter and just trying to work out what size. My pattern is 14 squares by 12 squares and I've been looking at doing either 4in or 5in squares.
Using 4in squares the finished size will be roughly 56x48, slightly smaller than I wanted (I want to use it on a single bed). Using 5in squares it will be roughly 70x60, which is a better finished size.
However I'm concerned that the bigger size will be too big to easily quilt using a normal sized sewing machine. What's the largest size quilt you can quilt using a normal sewing machine?
