ive also noticed using june tailor spray baste that there are some battings that it just wont stick to. i have been taking the backing and taping it to the floor, then taping the batting down too. not solid, just a tiny piece here and there to hold it while it is stretched taut, and i use painters tape so it won't ruin fabric or my flooring. then after i get the top on and smoothed out i pin pin pin. seems to work well!
