I don't like basting. So much so that I would give up quilting if I had to do it again with pins. Hurts my back. I try to only buy fusible batting but if I can't get that or don't have it on hand, I'll glue baste. Regular school glue and water and brush it on and set it with an iron. Holds better than spray basting and it doesn't take your breath away like the spray. I do it on my cutting table in sections. Holds like a charm. Sometimes the edges will come loose so I just reglue if I need to. You could try that if you can iron minky. Iron doesn't have to be hot, hot - just hot enough to dry the glue. You might try that.
