I am in the process of making a 3 sectional 7' book shelve with the bottom portion being cabinets. I've chosen 3/4" MDF (medium density fiber) board for cabinet and shelve construction because of it's versitility, low cost and smooth appearance after painting. What are the advantages & disadvantages of using MDF? Can I use "1 X " stock with this MDF construction? Is plywoood better? Please respond.
