Can anyone help me figure out why I always seem to be cutting off my corners, my points are good, my 1/4 accurate. But when I go to join my blocks there is usually not the requisite 1/4 inch necessary to make the blocks look good.
Try sewing a scant 1/4". One thread shy of a 1/4. It may be in the pressing of the seams.
the "scant quarter inch" is really important, specially if you have several pieces in the block. Take a block that you had problems with and measure it. Does it come out exactly the right size? Pressing, (ironing) also makes a difference. It's important to press down with only a little movement side to side. Too much movement and it distorts the fabric specially if there are any bias edges.
when I am sewing a block with lots of pieces, I find using starch a very big help in avoiding distorting the fabric.
