These are great, well-made handkerchiefs! If you've seen my review of organic cotton handkerchiefs then you know I have a problem with my ironing board. . Mostly it's a friendship where he stays in his part of the house and I in mine. Fortunately, while other tissues require a gentle touch of a hot iron, this is not the case. I say they don't "require" it. They have slight creases right after drying, but nothing to cause them to warp. Bamboo flannel almost completely does not wrinkle immediately after drying. However, I don't need handkerchiefs that are absolutely perfect and wrinkle-free. My problem with folds has always been that regular cotton folds don't fold well or don't fit in your bag and as a result. Made from cotton flannel, these dresses fit perfectly and have a nice rectangular look. Now they even have a small advantage over bamboo, they are a bit thinner. So if the bamboo ones are too thick for you, these might suit you better. Aside from the fact that they hardly wrinkle, I love flannel because they are very soft. My nose runs at the thought of spicy food, including peppers. So having a reliable and soft handkerchief with you is not only necessary, but much better than serviettes, paper towels or serviettes (oops). These handkerchiefs are also cream-colored. I think it feels more natural compared to bleached white cotton and shows a little less obvious discoloration from anything you might rub against it :-). Besides, Jennifer is a pleasure to deal with. When something goes wrong with tissues, she helps fix it.
