Hi (I'm new here).  Just wanted to share the coaster box I made, since I haven't seen anything like it anywhere.  My kids insisted I make them coasters of Mario items (it began with a mushroom and went out of control).  Eventually we had so many that I needed a place to store them.  Anyway... I didn't use a pattern or anything, I just kept making Tetris shapes until I filled the size I needed.
There's nothing fancy about the bottom; I just did concentric squares.  You never see it anyway because the box is full of coasters.  I suppose I could draw up a pattern if anyone wanted it.
Thanks for looking.
