This is probably one the easiest woodworking projects you will find here. Although easy, a doormat is an equally important and useful item for households. As you can see in the image below, you will only need some 2X2 wooden boards and rope to build a simple doormat. This doormat is mostly useful for outdoor and porch. It will easily remove all the mud from your shoes with just one wipe. It is also very easy to clean and looks fabulous even if it is dirty.
When the top is done, we want the edged MDF and the oak countertop to have exactly the same dimensions, and for their width to exactly match the width of the base.I could see three ways of doing this: 1, join the MDF to the countertop and use my belt sander to sand down their joined edges to match the base; 2, join the MDF to the countertop and use a hand plane to plane down their joined edges to match the base; or 3, use a flush-trim bit against a straight edge to route the MDF to the width of the base, then join the MDF to the countertop and use the flush-trim bit to route the countertop to match the MDF.
