JD....good for you! How nice you could help out your sis. I wish more girls learned how to do their own repairs. What I find the most aggravating are the trips back and forth to Home Depot. There use to be little local hardware stores, wish they still existed.
I take care of most problems in the house. Learned from my dad, and years as a homeowner not wanting to get ripped off. My dad use to say to me, "If you can take it apart, you can put it back together." I still need hubby to do heavy duty stuff.
