My client son is a biologist so the DNA design was perfect! It came out beautiful. I do have a suggestion … I would like to see the design redesigned so we can load the quilt sideways so the repeats will continue along the long length of the quilt. In the current design you need to ensure quilt is advanced perfectly straight and as the quilt shrinks you need to adjust width of the design so the strands are connected. I pieced the tshirt quilt so it was mostly square but not all quilt tops are square. Overall i still love the design and my client was over the moon happy!
