I have run basting lines. Just did it on the current quilt, and they came out fine. Of course,I am not doing elaborate quilting.
What keeps me from glue basting is that on a larger quilt, there just isn’t that much extra water in the tub for me to feel confident that the glue can really wash away and not migrate back into the batting.
I have an old Whirlpool with a large tub and also a Speed Queen that fills fully with water, so not sure what other washer would provide more assurance. I do know that I nearly destroyed a quilt with a pre-washed, dark batik that bled onto the front. Color catchers were used, but if there isn’t enough extra water, they can become trapped between the folds of the quilt and never do a great job.
Just saying,
