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.
Actually the song was written by Bruce Springsteen. Revved up like a deuce is referring to being excited in a manner similar to way 32 Ford Coupe (A deuce coupe) motor would be. A deuce is referring to the 1932 Ford Coupe which is an iconic hot rod known to enthusiasts as a deuce coupe or just deuce. So, revved up like a deuce would mean amped up, or wound up and ready to go, like a driver revving their engine while waiting to start the race.
