This is my first self-drafted block! I took the idea from the triple-stitched "solid square" & another Eaton block, "pin stripes" (which I haven't featured yet), combined them a bit, but increased one colour & decreased the other. The centre starts with a solid bit of light blue, and then a thin stripe of dark blue, and continued, decreasing the stitch size of that light blue from a treble down to a double (with a row of half treble in there) & increased the navy blue in proportion. I quite like it. It might work well as an alternative with Block #6, the Solid Square in blue, or even Square Target in a blue.
Stitched in Sirdar Baby, acrylic 4 ply.
