re: Oops

I like the ding the other 3 corners approach. 

BTW, the wet rag and iron method works well for dents in flat surfaces but you have to be careful using heat on a glue joint.  PVA wood glue will melt and the joint will be ruined if it gets too hot.  I use a heat gun to un-glue joints and remove PVA glue from bad repair jobs.  It doesn't take much heat to make the glue fail.  Heat and moisture will loosen hide glue joints too but you can reclamp the joint and the glue will readhere.
