I have used it to baste and secure quilts before I longarm whatever design I am going to quilt. Once I have basted in several places both across and down the quilt, I roll the quilt and continue basting leaving the approximately the last row unbasted. I then can roll the basted quilt (back, quilt top and the batting) sandwich back onto the the top bar (on my frame it is the backing bar).
I put the vanish thread on the top and in the bobbin. Don't have to worry to much about the tension.
The beauty is that it is disappears when you wash the quilt, Love it!!
