I have been wanting  picture shelf for my foyer for a while so I was happy to find these shelves.    I bought 2  4 foot shelves and hung them together to make an 8 foot shelf to go over the door in my 2 story foyer.   These shelves will be great for hanging art and changing pieces for the season or holiday.   They are made of a pressed particle board but are sturdy.   I had to change the holes based on where my studs are but had no problem drilling through the wood.   Overall I am very happy with this purchase.
