I’m a new sewer and have rocked along pretty well reading patterns and figuring them out by trial and error, but “sleeve vents” have me stumped. I can’t even figure out what they are by googling them- everyone seems to think you already know what they are.
1.) What IS a sleeve vent?
2.) Why do you “slash” it, and does that just mean cutting it?
3.)If it says to find where it is marked on the pattern, and there is only one small mark on the sleeve pattern about 2" in from the underarm edge, is that it?
4.) How far do you slash it? Most of the sites I’ve looked at mention 3-4" slashes- the marking on the pattern (Burda V-neck dress #107) is only about 1 cm long.
Please take pity on a newbie… this is my first major roadblock.
