Trust yourself.
I wanted a serpentine down each alternating strip of my new quilt top, but I didn't trust that I could do it myself, so I used the machine stitch. It looks nice, but after doing three strips, it just isn't quite what I had in mind, so I took the plunge and did one strip myself FMQ, thinking I can always rip it out.
Well, now I have three long strips of machine serpentine to tear out, because mine looks just like what I wanted.
So, ladies and gentlemen, trust yourself and your skills and your vision of what you want on your quilt and you'll be pleasantly surprised, like I was.
Have a great day!
