Cotton is a fiber (from the cotton plant). Flannel is a finish or weave. Hence you can have flannel wool as well as cotton flannel - i.e wool made with flannel finish or cotton made with flannel finish. Hope this helops.
A very memorable song from Joni Mitchell that featured the line They paved paradise and put up a parking lot.. This best described places I remember growing up in Bloomington, MN in my teens where numerous places were torn down, most notably a restaurant I frequented that was replaced with a Park and Ride lot.
Lyrics: Robert M. McCheyne. Music: Richard Redhead. When this passing world is done. When has sunk yon glorious sun. When we stand with Christ on high. Looking oâer lifeâs history.
