I like to experience all the methods once..this is what I have tried...
I have used pins...it's ok..but hurts to open and close them after a while...
then I tried the gun with the little plastic fasteneres..ok but a pain to cut them off...
then I tried glue basting..I like it a lot...
I tried hand basting..by taping the backing down, then the batting and the top..hard to keep it all spread out...
I tried Sharon Shamber's method using the boards..you can watch it on You Tube and I really really like this method...for all of the reasons explained in the videos...and I got good results....
I think spray basting with 505 is the easiest.. I am not fond of the chemicals...but definitely will use this method and Sharon's
