I have 4 nails in a hallway wall along the ceiling line. When it's time to baste a quilt, using a small step ladder, large binder clips are hung from those nails. 1) clip backing to the clips (RS to the wall) 2) clip batting to the clips.....STAND BETWEEN them and spray baste. It doesn't take a lot. Step out, smooth your two layers. 3) clip quilt top to the clips (WS to batting-RS toward you). STAND BETWEEN batting and quilt top and spray baste. Take the quilt down, lay in on a flat surface and do some minor adjustments. I usually put a few pins along the outside edge. Just did this method with a friend using Dritz spray baste. It had no smell and worked just as well as mine. I use Ann Tailor...it does smell...but I like that :-)
