help identify this technique
This is the second quilt that I have created the blocks using this technique, but I don't know how to describe it. I'm sure the process has a name. I feel confident that someone will be able to identify the name if I can communicate my process coherently. It starts with a square base piece, and then I stitch a scrap of fabric, press, and trim. Then add next strip of scrap on top of that one, stitch, press, trim, repeat until section is filled. TIA
