what season is it?

I know it is still summer. I can tell by the sun, the heat, the sand in the sheets. But at my work table, the season is changing. I am fortunate in that I do not have to sew 2 seasons ahead, as for a collection. I can slowly work into the next weather pattern. These are the beginning of the transitional pieces: heavier linens, cottons....soon to be followed by twills, corduroy?, light-weight wools. 'Putting off the transition as long as possible. Linger longer, summer.
