Typo error – should be “efficiency” instead of “effiency”. I drew these using the Paper app by 53 but was reminded as I tried to save the old drawings how fiddly and challenging the app was. It didn’t have a layers function and that is really such a no-no to me now (makes me feel so much more professional to be able to say that now!).
My silent killers can sometimes fail to be silent 🙄 but it’s better now that I no longer plug in to my headphones as I used to. I mean, I no longer attempt it in public 😁
