23) For me, sometimes the "slower", apparently more inefficient ways have worked out better.
Examples:
Washing and ironing/pressing fabric before cutting -
Rotary cutting single layers rather than multiple layers because I feel that my cuts are more accurate. (And if I do measure wrong, it's less fabric wasted)
Of course, it may be that my blade is dull and needs to be changed.
Trimming/squaring HSTs before going on to the next step. There probably are more efficient ways to do them, but this seems to be working. And cutting +1 inch instead of +7/8 inch definitely helps me.
