Jikes this weekend? you must be running around like some kinda mad woman trying to tie up any loose ends...I know thats how it is when I do anything volunteer like for my sons school
I am sure the kids will LOVE LOVE LOVE the playdough.
So this suggestion isnt school safe BUT my all time fav grocery bag, which I ordered online from Alternative Outfitters, says "Shop with a reusable bag B#%*h" the word is NOT spelled out and I get so many positive comments on it.
Good luck this weekend
