Fabrics for Mei Tai body and straps
Keep in mind that some of these fabrics come in different weights. You want something that is pretty substantial.
Twill
Pros: soft, pliable, yet strong, can be dressed up since it's a smooth-textured fabric
Cons: wrinkles easily and straps bunch up; doesn't hold its shape as well
Denim
Pros: soft, strong
Cons: darker colors fade, making it more casual
Canvas and duck
Pros: strong, softens up nicely after pre-wash, stiffer so holds its shape well.
Cons: rougher texture
Corduroy
Pros: soft, strong, warm
Cons: may be too warm, fabric has lots of friction so may be harder to tie and untie
