I have a 4 ft x 4 ft particle board sewing table that was custom made for me. It is in good shape other than the 4x4 bottom. The wheels got caught in carpeting and the edges on one side has broken off in several pieces. That same piece has a hairline crack down the middle. I am looking for someone to duplicate this bottom piece or repair it. I have read that it could fixed by using some type of "plaster filling"; however, I think replacing it would be the best fix. It has a large + about 1" wide cut so that the middle boards nestle in the bottom.
