Last night while working on the windows, my son refilled my tea sippy (a cup with a screw on lid and a straw) but didn't secure the lid.. I didn't notice, and went to pick up the cup to take a sip. The cup slipped out of my hands and spilled tea all over my doll house wall. He grabbed a towel to help mop up the mess. The majority of it wound up in this silver tray that was sitting on top of the doll house part, that held tools (tweezers of all sorts, a mirror on a telescopic stick, swabs, and face masks) needless to say it took me a bit to clean up the mess and dry off the part of the doll house. This morning I began applying primer to the doll house walls and noticed one wall developed a crack. The crack doesn't go all the way through the board, fortunately. I don't know if I need to try to repair it, or if it will be ok, my concern is that this will weaken the construction of that wall. I suppose I could try to staple it back together on that side of the wall to strengthen it. Any other ideas?
