I would not change it mainly because when I was a little girl my Gramma had me learn to hand stitch before 'machining'-(her word,not mine) and as the project grew we could see how my hand sewing had improved and the same project was also machined to help me learn to get seams matched etc.So no I wouldn't change it or round file it.I lost that project full of memories of my Gramma in a house fire years ago,and still miss seeing it proudly displayed on the back of the couch
