I longarm, and Dunster is right. Shouldn't be a problem. I have done a bunch of quilts out of clothes for people. I've used my robot and freehand both. I just pay attention and slow down. Just be mindful of pressing correctly and trimming loose threads. Also, let your longarmer know if you used stabilizer just as a heads up. My machine will sew anything when I take my time, but not all machines are the same.
What you are doing looks great.
