I used spray baste for the first time yesterday, and I have June Tailor. It was a bit wrinkled so I had to peel it apart and re-smooth out several sections. But I thought it was just my inexperience that caused it. Or maybe that spray basting works better on smaller quilts (this one is lap sized). I'm tying this quilt, so I guess I won't know what it does to my machine. One thing I did notice is that it's not keeping the edges together. I think I'm going to pin along the border before I start tying.
But now I'm nervous using the spray basting spray on my next quilt!
