I pin..... I am still learning to FMQ... so I just do a small area at a time anyway and removed pins as I go.
I have the spray baste.. but even protecting the outer areas , the over spray went EVERYWHERE!!!! I never adjusted to the spray....
I have a pair os stainless steel long handle tweezers that I use now when I HAVE to spray ( & I go outdoors) that I have tried just about everything I can think of to clean the left over spray basting off of them.... Even Goo B Gone and Acidtone didnt get it off.....
