Asashi and his pasty-white man-thighs?
I don't think you have much to worry about. Chances are good that you'll look more badass than half the people in IG simply by giving a ****.
And yes, hand-stitching is not fast. But it does get faster with practice.
Athron sat and watched me sew together an axe-head cover one day, then told me it made him feel much better having watched, because it made him realize that even experienced seamstresses take a long time handsewing things. He just thought it was inexperience.....but it's not. Hand-sewing is just slow.
