Sugar Cookies

I got a request to make about 100 sugar cookies for a lady that wanted to buy them from me to give away for Christmas so my husband and I spend the last 2 days making and decorating cookies.
It's a pretty good recipe so here it is:

2 Cups Sugar
1 Cup Sour Cream
1 Cup Butter softened
Cream that together and then add
3 Beaten Eggs
1 tsp Salt
1 tsp Baking Soda
4 tsp Baking Powder
6 Cups Flour

Cool in Fridge for an hour and then roll out and cut into fun shapes
bake at 350 for 7-9 minutes
