Using your fabric efficiently? Makes total sense. No objection to that.

But specifically designing patterns such that every single part of a length of fabric is consumed by it? You're setting people up to fail. For one, you can really only do this with patterns made mostly of rectangles and right triangles, which can only make a very narrow range of garments that simply do not play nice with many people's bodies (especially bodies with lots of curvature). For another, a zero-waste pattern is also a zero-error-tolerance pattern. One wrong cut or measurement and the whole thing's toast. The wiggle-room that a more standard pattern allows also allows you to fix problems when they occur.

If you make a zero-waste garment and never wear it because it looks bad on you? That's not actually zero-waste. If you start a zero-waste garment and can't complete it because you made one little mistake? That's not actually zero-waste.

But more importantly, the whole idea of 'zero-waste' as a desireable outcome is antithetical to the methods and traditions of sewing. It's a form of functionless, guilt-driven, aesthetics-first minimalism that has no place in actual sewing practice. The scraps of fabric left over from cutting a pattern are incredibly useful. Larger pieces can become parts of new projects. Smaller pieces can become patchwork. Even really tiny scraps can become stuffing or batting or kindling or any number of other things. Home sewing has always been about not wasting things, but the way to not waste things is not by piously making only garments that suck, it's by repurposing, reusing, and recycling everything you buy. Once that fabric reaches your house, 98% of its environmental impact has already happened.

Lance, mocking Fernando: When I was your height. 

Fernando: 

Damian: Grayson, why does Pennyworth leave food on the counter every night?

Dick, on his phone, not even paying attention: Oh, that's for Jason.

Damian: For 'Jason'?

Dick: Yeah. Sometimes he sneaks into the kitchen at night, so Alfred started leaving food out for him.

Damian, confused: I've never seen anyone here.

Dick: Well he doesn't always come. And last time, Bruce caught him crawling through the window and scared him away so, who knows when he'll show up again.

Damian, definitely thinking of a raccoon: So then Pennyworth is feeding a random stray that crawled out of God knows where?

Dick, annoyed: He's not a 'random stray', Damian, he's family, and he has been living in this house for way longer than you have.

Damian, trying to remember how long do raccoons live for:

Damian: I hope he doesn't die soon.

Dick: ????!!

*Later that night in the Bat-cave*

Tim, typing away in the computer:

Damian: Drake. Have you ever met Jason?

Tim: Uh. Stupid, annoying and looks like a skunk? Yes, why?

Damian, picturing a mix between a racoon and a skunk:

Damian: Is he friendly?

Tim: Well, the first time I met him, he attacked me, so...

Damian: Hmm... What did you do to provoke him?

Tim: What did I do to– Bitch–

Tim: Nothing! He just didn't like me taking 'what was his', or something.

Damian, nodding: You invaded his territory.

*The next day*

Damian: Father, when do you think Jason will visit again? I want to meet him.

Bruce: Um. I don't know, Damian. He doesn't come here often.

Damian: Why?

Bruce: Because he lives somewhere else.

Damian: Why doesn't he just live here with us instead? He would be safer.

Bruce, wincing: I don't think he would like that, Damian. He's not confortable here.

Damian: But, maybe if I befriend him I could convince him to stay.

Bruce, sighing: I don't think so, Damian. You have to respect his space.

Damian: Oh...

Damian: I hope he doesn't get rabies
