Aprons have been around forever and a day. They are used to protect one's clothing when performing various household tasks. In its most recent return to popularity, even men are known to wear aprons and why not, it protects everyone's clothing and we know cooking is no longer the domain of the woman.
With Mother's day approaching, finding a lovely apron that your mother will enjoy wearing should not be too difficult. I would mix it with a few flowers just to show her how appreciated she really is. It is not enough to underline the fact that she kept you fed and watered, it is also great to acknowledge her as a lady - a lady you love.
