I wanted to get a desk for my son, and I went to 5 different stores only to find out that most desks are 47" wide and the space I had to fill is 45". So I built one. Bought a 48 x 24" sheet of MDF, cut 3" off of the end and attached brackets for screw-in legs. Boom. It’s a little wobbly, but it’ll do, and it was a lot less than buying a desk. The prefab legs were a bit spendy ($10 each), but the board was only $12, brackets $8. The lamp set me back $5 at Salvation Army.
