Brigitta,
I use large plastic bags tied with a twist tie. Most of my breads
are not in pans. I place the shaped loaves on a couche on an
overturned half sheet pan. I place this into a large plastic bag,
trap air in it as best I can, then tie the neck of the bag with a
twist tie. If the dough is sticky, I will put some flour on the top
of it. I seldom have trouble with the bag sticking. That way the
shaped dough stays moist. If using pans, I will do the same thing
with smaller bags or I will put a few pans on the half sheet pan and
put that into a large plastic bag.
Hope this helps,
Dave Glaze
