I'm a total chicken when it comes to doing my own machine quilting. I only tried it with my Brother---which the bobbin casing just spazed out and from what I've read, better to junk it than attempt to fix. I have a Janome but I haven't experimented with it. Don't know if I'll get around to it.
I'm happy for you that you did your own work. It gives such a sense of accomplishment. Good for you! I think it looks just fine the way it is. As you do more, these earlier projects are now part of your quilting history, something to look back at how it all began. Keep up the awesome work!
