Hi I am new here, I have been quilting for over 30 years.
I also own a long arm quilting machine.
I just wanted to say that I hand quilt also, and baste my quilt on my longarm. I used to do this for customers for about $30.00. Saves lots of back breaking pinning and bending.
Also wanted to say that the quilt looks great, and I would not fix the patch out of place. I love uniqueness in a quilt and rarely fix mistakes. I leave them in place for a reminder of how only God is perfect.
I agree with the other hand quilter, straight lines are a great way to begin learning handquilting. If you begin with lots of twisting and turning, because of your inexperience, you may not want to continue.
Good luck
