This stitch is called the Shell Network.
I made a scarf with this stitch. This one stitched up very fast.
My samples are getting larger and larger. Need the bigger size just to show the pattern. This one is called Block and Offset Shell.
Because the pattern is so large on this one, I made a lap blanket instead of a scarf. Took forever because I really didn’t like this pattern. It just looks like stripes from two different blankets pieced together.
