I like your suggestion! Strangest thing is there is no sizing given for the units, only a finished size for each finished block! Just tells me what size to cut my strips/squares from each fabric, then cut each square corner to corner and sew together "as shown". I totally keep looking for what size each unit is supposed to end up as I'm working through each block, but it's not there! Do you think I should deconstruct these units completely and re-sew? I already know I need to re-cut half of the larger yellow triangles because they're just flat out too short on one side. Not sure how I did that. But there ya go. Maybe just take off the large triangles from all and "re-square" up the center triangular unit by wetting them down, etc, before sewing the large triangles back on?
