Norbana,
Thanks so much, sorry I didn't reply sooner as my dil came up and we ended up spending the rest of the evening together and I didn't get back online.
I really like what you've done.
You said each of the rails were 1" did you mean 2" perhaps?
I ask because the students may be writing on the upper or lower rails and 1" wouldn't be wide enough for them I'm afraid.
I really like how this looks and thank you again for giving me a better view.
Muriel
