Well I would tell you to forget that Crease free pipe dream. I have some extra blankets and sheet stored in those vac bags in the camper to take up less space and they really work for that but are very wrinkled. For your stuff it might work if you didn't draw as deep a vacuum and maybe leave just a little air in the bags. I would be very careful of any necks or saddles that you would put in these bags because they might really get crushed. You might experiment with some of the bags and some stuff that isn't very important just to see how drawn up these bags can get.
