You know how you're "supposed" to do a lead strip where you sew onto scrap fabric, then sew onto your real pieces, then finish on a scrap? The idea being something about... ya know, I don't know why you're supposed to do it, I just know that I minimize the bird's nests when I start. Maybe that's it.
Anyway, why this is relevant: I am making a quilt out of 1.5" squares. Only 1.5" squares. Rather than using scraps as the leaders, I have a pile of squares and I sew 2 together, then sew my regular pieces, and end by sewing 2 together. I've gone through probably about 100 and that was without actively sewing them, ya know? So now I just need to iron them all, and then they go back through the rotation and get sewn again. So this way, I'll have a beautiful quilt of tiny squares and it was no big deal to do!
