Coffee table DIY projects using Acrylic Plastic Sheets is the perfect way to re-purpose and old coffee table or upgrade a flea market find. There are different colors of plastic sheeting as well as frosted with a design element in the sheet for you to choose from.
If your coffee table already has a glass top remove it and then do a refinishing on the wood. Be sure to measure the glass you removed first. You can do a light sanding and seal, or bring the wood down to raw color. When you bring the wood down to a raw state you can change the stain of the wood then finish with a polyurethane coating. After the coating dries insert the new Plexiglas piece that you have picked out. A thicker sheet may be helpful if you are replacing a large piece of glass with the Plexiglas usually they have weight ratings listed where you purchase them.
With very little effort you can have a beautiful new coffee table in less than a day.
