You seem upset <| sep |> Haha I ' m a doula and that ' s the problem I ' m having . In theory , I mnkw what contractions sound like , but not what they feel like because this is my first so I have no idea . I would tell my client to call Ld but I ' m so convinced I ' m going to be told to go in and then just have a big fart . <| sep |> As a rule , avoid polyacrylic , it is a garbage substitute for wool , able to simulate loft but has no real advantages in regards to comfort , warmth , durability , etc . Polyester is added to reduce fiber cost and add durability . Not all polyesters are the same but , in general , they add wrinkle resistance , decrease breathability , and have kind of a gross hand . Elastane will give you stretch in a woven fabric . Polyamide Nylon is durable , drapes well , is shiny , and uncomfortable . Rayon Bamboo , Viscose , Modal , A billion other names is a synthetically produced cellulose fiber that can have a very soft hand varying between cotton and silk . Wrinkles like a bastard , has dimensional stability issues , but is breathable and comfortable .
