Anybody made a postage stamp quilt? I'm having some trouble matching corners. I've made many scrappy square quilts with bigger pieces and can always ease the pieces if they don't want to nest properly, but some of these little pieces won't nest and my corners aren't all right. I do cut accuratly and I can sew a decent 1/4 inch seam. This is driving me nuts, what am I doing wrong? Is there a technique I don't know? I'm using 2 inch strips, finishing 1.5 inch. Am I being too picky? I have finished 20 blocks so far. Help!
