plain fabric for backing
 

I quilt on longarm using pantographs my stiches arent always perfect I usually use busy fabric stitches don't show what do you think should I try it or not??

Sure why not! I used pantos before I splurged on robotics and most of my quilts are backed with muslin. I use thread that matched the backing and was happy with the results.

se thread that blends with the backing fabric. Or don't. it really doesn't matter in the end, as long as the stitches hold it all together!

Heck, I use my domestic machine with a walking foot. Muslin is my favorite backing although I sometimes use yardage or make a scrappy back. Muslin is nice and soft and, yes, my stitches show, wobbles and all. It's evidence that a human made the quilt and not a machine.

Thanks for the reminder, Mkotch. We are humans and although we strive for a job well done, the apparent perfection of a manufactured quilt is not our goal.

When a quilt is washed and it crinkles, the wobbles, wiggles, and less than "perfect" quilting disappears. We know it is there but most other folk don't. A print on the back of a quilt hides small errors, agreed. I use muslin, small prints and matching thread. I have stumbled on how easily very light gray or very light tan thread can disappear into a print so my imperfections are not as apparent. I do about 80 % of my own quilting but even quilts that go to a long arm quilter not "perfect." and that's OK too.

I FMQ on a domestic machine. I'm good at it, but not great. I'm more concerned about the front looking good than the back, but I do use thread that matches the backing and it makes oops's less noticeable.

thanks for the response I am going to try it

I also do my own FMQ on my Janome. I usually use a backing fabric that has some kind of a pattern so my "bloops" don't show.

Because I plan to use leftovers to construct a back, buying extra for front gives me freedom to make decisions as the project progresses.
