Which Summer and Winter?

My title doesn't make any sense, since, or huh???  The weaving for this four blocks on four shafts of summer and winter is going fairly quickly. At least when I am home and can get to the loom. Looks like the 20 inch mark was half way.

 



This is how I am keeping track of which part of which block and which color to use. Which, I am sure you know, is very important! Which is why I am stopping today.
